General Description
The MIC37100, MIC37101, and MIC37102 are 1A low
dropout, linear voltage regulators that provide low
voltage, high current output from an extremely small
package. Utilizing Microchip’s proprietary Super βeta
PNP pass element, the MIC37100/01/02 offers
extremely low dropout (typically 280 mV at 1A) and low
ground current (typically 11 mA at 1A).
The MIC37100 is a fixed output regulator offered in the
SOT-223 package. The MIC37101 and MIC37102 are
fixed and adjustable regulators, respectively, in a
thermally enhanced power 8-pin SOIC (small outline
package). The MIC37102 is also available in the S-PAK
power package, for applications that require higher
power dissipation or higher operating ambient
temperatures.
The MIC37100/01/02 is ideal for PC add in cards that
need to convert from standard 5V to 3.3V, 3.3V to 2.5V
or 2.5V to 1.8V or lower. A guaranteed maximum
dropout voltage of 500 mV over all operating conditions
allows the MIC37100/01/02 to provide 2.5V from a
supply as low as 3V and 1.8V from a supply as low as
2.3V.
The MIC37100/01/02 is fully protected with overcurrent
limiting and thermal shutdown. Fixed output voltages of
1.5V, 1.65V, 1.8V, 2.5V and 3.3V are available on
MIC37100/01 with adjustable output voltages to 1.24V
on MIC37102.

Note 1: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the
maximum allowable power dissipation will cause the device operating junction temperature to exceed the
maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.

4.0 APPLICATION INFORMATION
The MIC37100/01/02 is a high-performance low
dropout voltage regulator suitable for moderate to high
current voltage regulator applications. Its 500 mV
dropout voltage at full load and overtemperature makes
it especially valuable in battery powered systems and
as high efficiency noise filters in post regulator
applications. Unlike older NPN-pass transistor designs,
where the minimum dropout voltage is limited by the
base-to-emitter voltage drop and collector-to-emitter
saturation voltage, dropout performance of the PNP
output of these devices is limited only by the low VCE
saturation voltage.
A trade-off for the low dropout voltage is a varying base
drive requirement. Microchip’s Super βeta PNP
process reduces this drive requirement to only 2% of
the load current.
The MIC37100/01/02 regulator is fully protected from
damage due to fault conditions. Linear current limiting
is provided. Output current during overload conditions
is constant. Thermal shutdown disables the device
when the die temperature exceeds the maximum safe
operating temperature. The output structure of these
regulators allows voltages in excess of the desired
output voltage to be applied without reverse current
flow.
FIGURE 4-1: Capacitor Requirements.
4.1 Output Capacitor
The MIC37100/01/02 requires an output capacitor to
maintain stability and improve transient response. As a
µCap LDO, the MIC37100/01/02 can operate with
ceramic output capacitors as long as the amount of
capacitance is 10 µF or greater. For values of output
capacitance lower than 10 µF, the recommended ESR
range is 200 mΩ to 2Ω. The minimum value of output
capacitance recommended for the MIC37100/01/02 is
4.7 µF.
For 10 µF or greater the ESR range recommended is
less than 1Ω. Ultra-low ESR ceramic capacitors are
recommended for output capacitance of 10 µF or
greater to help improve transient response and noise
reduction at high frequency. X7R/X5R dielectric-type
ceramic capacitors are recommended because of their
temperature performance. X7R-type capacitors
change capacitance by 15% over their operating
temperature range and are the most stable type of
ceramic capacitors. Z5U and Y5V dielectric capacitors
change value by as much as 50% and 60%
respectively over their operating temperature ranges.
To use a ceramic chip capacitor with Y5V dielectric, the
value must be much higher than an X7R ceramic
capacitor to ensure the same minimum capacitance
over the equivalent operating temperature range.
4.2 Input Capacitor
An input capacitor of 1 µF or greater is recommended
when the device is more than 4 inches away from the
bulk ac supply capacitance or when the supply is a
battery. Small, surface mount, ceramic chip capacitors
can be used for bypassing. Larger values will help to
improve ripple rejection by bypassing the input to the
regulator, further improving the integrity of the output
voltage.
4.3 Error Flag
The MIC37101 features an error flag (FLG), which
monitors the output voltage and signals an error
condition when this voltage drops 5% below its
expected value. The error flag is an open-collector
output that pulls low under fault conditions and may
sink up to 10 mA. Low output voltage signifies a
number of possible problems, including an overcurrent
fault (the device is in current limit) or low input voltage.
The flag output is inoperative during overtemperature
conditions. A pull-up resistor from FLG to either VIN or
VOUT is required for proper operation. For information
regarding the minimum and maximum values of pull-up
resistance, refer to FIGURE 2-28: “Error Flag Pull-Up
Resistor.”in the 2.0 “Typical Performance Curves”
section of the data sheet.
4.4 Enable Input
The MIC37101 and MIC37102 versions feature an
active-high enable input (EN) that allows on-off control
of the regulator. Current drain reduces to “zero” when
the device is shutdown, with only microamperes of
leakage current. The EN input has TTL/CMOS
compatible thresholds for simple logic interfacing. EN
may be directly tied to VIN and pulled up to the
maximum supply voltage.
4.5 Transient Response and 3.3V to
2.5V or 2.5V to 1.8V, 1.65V or 1.5V
Conversion
The MIC37100/01/02 has excellent transient response
to variations in input voltage and load current. The
device has been designed to respond quickly to load

current variations and input voltage variations. Large
output capacitors are not required to obtain this
performance. A standard 10 µF output capacitor, is all
that is required. Larger values help to improve
performance even further.
By virtue of its low dropout voltage, this device does not
saturate into dropout as readily as similar NPN-based
designs. When converting from 3.3V to 2.5V or 2.5V to
1.8V, or lower, the NPN based regulators are already
operating in dropout, with typical dropout requirements
of 1.2V or greater. To convert down to 2.5V or 1.8V
without operating in dropout, NPN-based regulators
require an input voltage of 3.7V at the very least. The
MIC37100 regulator will provide excellent performance
with an input as low as 3.0V or 2.5V respectively. This
gives the PNP based regulators a distinct advantage
over older, NPN based linear regulators.
4.6 Minimum Load Current
The MIC37100/01/02 regulator is specified between
finite loads. If the output current is too small, leakage
currents dominate and the output voltage rises. A
10 mA minimum load current is necessary for proper
regulation.
4.7 Adjustable Regulator Design
FIGURE 4-2: Adjustable Regulator with
Resistors.
EQUATION 4-1:
The MIC37102 allows programming the output voltage
anywhere between 1.24V and the 6V maximum
operating rating of the family. Two resistors are used.
Resistors can be quite large, up to 1 MΩ, because of
the very high input impedance and low bias current of
the sense comparator. The resistor values are
calculated by:
EQUATION 4-2:
Where VOUT is the desired output voltage. Figure 4-2
shows the component definition. Applications with
widely varying load currents may scale the resistors to
draw the minimum load current required for proper
operation.
4.8 Power SOIC-8 Thermal
Characteristics
One of the secrets of the MIC37101/02’s performance
is its power SO-8 package featuring half the thermal
resistance of a standard SO-8 package. Lower thermal
resistance means more output current or higher input
voltage for a given package size.
Lower thermal resistance is achieved by joining the
four ground leads with the die attach paddle to create a
single piece electrical and thermal conductor. This
concept has been used by MOSFET manufacturers for
years, proving very reliable and cost effective for the
user.
Thermal resistance consists of two main elements, θJC
(junction-to-case thermal resistance) and θCA
(case-to-ambient thermal resistance). See Figure 4-3.
θJC is the resistance from the die to the leads of the
package. θCA is the resistance from the leads to the
ambient air and it includes θCS (case-to-sink thermal
resistance) and θSA (sink-to-ambient thermal
resistance).

Using the power SOIC-8 reduces the θJC dramatically
and allows the user to reduce θCA. The total thermal
resistance, θJA (junction-to-ambient thermal
resistance) is the limiting factor in calculating the
maximum power dissipation capability of the device.
Typically, the power SOIC-8 has a θJC of 20°C/W, this
is significantly lower than the standard SOIC-8 which is
typically 75°C/W. θCA is reduced because pins 5
through 8 can now be soldered directly to a ground
plane which significantly reduces the case-to-sink
thermal resistance and sink to ambient thermal
resistance.
Low dropout linear regulators from Microchip are rated
to a maximum junction temperature of 125°C. It is
important not to exceed this maximum junction
temperature during operation of the device. To prevent
this maximum junction temperature from being
exceeded, the appropriate ground plane heat sink must
be used.
FIGURE 4-4: Copper Area vs. Power
SO-8 Power Dissipation.
Figure 4-4 shows copper area versus power
dissipation with each trace corresponding to a different
temperature rise above ambient.
From these curves, the minimum area of copper
necessary for the part to operate safely can be
determined. The maximum allowable temperature rise
must be calculated to determine operation along which
curve.
EQUATION 4-3:
For example, the maximum ambient temperature is
50°C, the ΔT is determined as follows:
EQUATION 4-4:
Using Figure 4-4, the minimum amount of required
copper can be determined based on the required
power dissipation. Power dissipation in a linear
regulator is calculated as follows:
EQUATION 4-5:
If we use a 2.5V output device and a 3.3V input at an
output current of 1A, then our power dissipation is as
follows:
EQUATION 4-6:
From Figure 4-4, the minimum amount of copper
required to operate this application at a ΔT of 75°C is
160 mm2.
4.9 Quick Method
Determine the power dissipation requirements for the
design along with the maximum ambient temperature
at which the device will be operated. Refer to
Figure 4-5, which shows safe operating curves for
three different ambient temperatures: 25°C, 50°C and
85°C. From these curves, the minimum amount of
copper can be determined by knowing the maximum
power dissipation required. If the maximum ambient
temperature is 50°C and the power dissipation is as
above, 836 mW, the curve in Figure 4-5 shows that the
required area of copper is 160 mm2.
The θJA of this package is ideally 63°C/W, but it will
vary depending upon the availability of copper ground
plane to which it is attached.
