Explanation of Terms
1. Low Dropout Voltage Regulator
This voltage regulator has the low dropout voltage due to its built-in low on-resistance transistor.
2. Low ESR
Low ESR means the Equivalent Series Resistance of a capacitor is small. The low ESR ceramics
output capacitor (CL) can be used in the S-L2980 Series. A capacitor whose ESR is 10 or less
can be used.
3. Output Voltage (VOUT)
The accuracy of the output voltage is ensured at 2.0 % under the specified conditions of fixed input
voltage*1, fixed output current, and fixed temperature.
*1. Differs depending upon the product.
Caution If the above conditions change, the output voltage value may vary and exceed the
accuracy range of the output voltage. Refer to the “ Electrical Characteristics” and
“ Typical Characteristics” for details.

Operation
1. Basic Operation
Figure 11 shows the block diagram of the S-L2980 Series.
The error amplifier compares the reference voltage (Vref) with feedback voltage (Vfb), which is the output
voltage resistance-divided by feedback resistors (Rs and Rf). It supplies the gate voltage necessary to
maintain the constant output voltage which is not influenced by the input voltage and temperature
change, to the output transistor.

2. Output Transistor
In the S-L2980 Series, a low on-resistance P-channel MOS FET is used as the output transistor.
Be sure that VOUT does not exceed VIN 0.3 V to prevent the voltage regulator from being damaged due
to inverse current flowing from the VOUT pin through a parasitic diode to the VIN pin.

3. ON/OFF Pin
This pin starts and stops the regulator.
When the ON/OFF pin is set to OFF level, the operation of all internal circuits stops, the built-in P-
channel MOS FET output transistor between VIN pin and VOUT pin is turned off to make current
consumption drastically reduced. The VOUT pin becomes the VSS level due to internally divided
resistance of several hundreds k between the VOUT pin and VSS pin.
Furthermore, the structure of the ON/OFF pin is as shown in Figure 12. Since the ON/OFF pin is
neither pulled down nor pulled up internally, do not use it in the floating state. In addition, please note
that current consumption increases if a voltage of 0.3 V to VIN–0.3 V is applied to the ON/OFF pin.
When the ON/OFF pin is not used, connect it to the VIN pin in case the product type is “A” and to the
VSS pin in case of “B”.

Selection of Output Capacitor (CL)
The S-L2980 Series needs an output capacitor between VOUT pin and VSS pin for phase compensation.
A ceramic capacitor whose capacitance is 1.0 F or more*1 can be used. When an OS (Organic Semi-
conductor) capacitor, a tantalum capacitor or an aluminum electrolyte capacitor is used, the capacitance
should be 2.2 F or more and the ESR should be 10 or less.
The value of the output overshoot or undershoot transient response varies depending on the value of the
output capacitor.
Sufficient evaluation including temperature dependency in the actual environment is needed.
*1. If the product whose output voltage is 1.7 V or less will be used, the capacitance should be 2.2 F
or more.

Precautions
Wiring patterns for VIN pin, VOUT pin and GND pin should be designed to hold low impedance. When
mounting an output capacitor between the VOUT and VSS pins (CL) and a capacitor for stabilizing the
input between VIN and VSS pins (CIN), the distance from the capacitors to these pins should be as short
as possible.
Note that output voltage may increase when a series regulator is used at low load current (1.0 mA or less).
Generally a series regulator may cause oscillation, depending on the selection of external parts. The
following conditions are recommended for this IC. However, be sure to perform sufficient evaluation under
the actual usage conditions for selection, including evaluation of temperature characteristics.
Input capacitor (CIN): 0.47 F or more
Output capacitor (CL): 1.0 F or more*1
Equivalent Series Resistance (ESR): 10 or less
Input series resistance (RIN): 10 or less
*1. If the product whose output voltage will be is 1.7 V or less is used, the capacitance should be 2.2 F
or more.
A voltage regulator may oscillate when the impedance of the power supply is high and the input capacitor
is small or not connected.
Overshoot may occur in the output voltage momentarily if the voltage is rapidly raised at power-on or
when the power supply fluctuates. Sufficiently evaluate the output voltage at power-on with the actual
device.
The application condition for input voltage, output voltage and load current should not exceed the package
power dissipation.
Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in
electrostatic protection circuit.
In determining output current attention should be paid to the output current value specified in the Table 4
for “ Electrical Characteristics” and the footnote *5.
ABLIC Inc. claims no responsibility for any and all disputes arising out of or in connection with any
infringement of the products including this IC upon patents owned by a third party.
