General Description
Ideal for space critical applications, the LM4040 and
LM4041 precision voltage references are available in
the subminiature SOT-23 surface-mount package.
The LM4040 is available in fixed reverse-breakdown
voltages of 2.500V, 4.096V, and 5.000V. The LM4041
is available with a fixed 1.225V or an adjustable
reverse-breakdown voltage.
The minimum operating current ranges from 60 A for
the LM4041-1.2 to 74 A for the LM4040-5.0. LM4040
versions have a maximum operating current of 15 mA.
LM4041 versions have a maximum operating current of
12 mA.
The LM4040 and LM4041 have bandgap reference
temperature drift curvature correction and low dynamic
impedance, ensuring stable reverse-breakdown
voltage accuracy over a wide range of operating
temperatures and currents.

† Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at those or any other conditions above those indicated
in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended
periods may affect device reliability.
‡ Notice: The device is not guaranteed to function outside its operating ratings.
Note 1: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX (max-
imum junction temperature), JA (junction-to-ambient thermal resistance), and TA (ambient temperature).
The maximum allowable power dissipation at any temperature is PDMAX = (TJMAX – TA)/ JA or the number
given in the Absolute Maximum Ratings, whichever is lower. For the LM4040 and LM4041, TJMAX = +125°C
and the typical thermal resistance, when board-mounted, is +326°C/W for the SOT-23 package.
2: Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5 k in series
with 100 pF. The machine model is a 200 pF capacitor discharged directly into each pin.

LM4040/LM4041
4.0 APPLICATION INFORMATION
The stable operation of the LM4040 and LM4041
references require an external capacitor greater than
10 nF connected between the (+) and (–) pins. Bypass
capacitors with values between 100 pF and 10 nF have
been found to cause the devices to exhibit instabilities.
4.1 Schottky Diode
LM4040-x.x and LM4041-1.2 in the SOT-23 package
have a parasitic Schottky diode between Pin 2 (–) and
Pin 3 (die attach interface connect). Pin 3 of the
SOT-23 package must float or be connected to Pin 2.
The LM4041-ADJ use Pin 3 as the (–) output.
4.2 Conventional Shunt Regulator
In a conventional shunt regulator application (see
Figure 5-1), an external series resistor (RS) is
connected between the supply voltage and the
LM4040-x.x or LM4041-1.2 reference. RS determines
the current that flows through the load (IL) and the
reference (IQ). Because load current and supply
voltage may vary, RS should be small enough to supply
at least the minimum acceptable IQ to the reference
even when the supply voltage is at its minimum and the
load current is at its maximum value. When the supply
voltage is at its maximum and IL is at its minimum, RS
should be large enough so that the current flowing
through the LM4040-x.x is less than 15 mA, and the
current flowing through the LM4041-1.2 or
LM4041-ADJ is less than 12 mA.
RS is determined by the supply voltage (VS), the load
and operating current, (IL and IQ), and the reference’s
reverse breakdown voltage (VR):
EQUATION 4-1:
4.3 Adjustable Regulator
The LM4041-ADJ’s output voltage can be adjusted to
any value between 1.24V and 10V. It is a function of the
internal reference voltage (VREF) and the ratio of the
external feedback resistors as shown in Figure 5-2.
The output is found using the following equation:
EQUATION 4-2:
The actual value of the internal VREF is a function of VO.
The corrected VREF is determined by:
EQUATION 4-3:
VREF/VO is found in the Electrical Characteristics
section and is typically –1.3 mV/V and VY is equal to
1.233V. Replace the value of VREF in Equation 4-2 with
the value VREF found using Equation 4-3.
Note that actual output voltage can deviate from that
predicted using the typical VREF/VO in Equation 4-3;
for C-grade parts, the worst case VREF/VO is –
2.5 mV/V and VY = 1.248V.
The following example shows the difference in output
voltage resulting from the typical and worst case values
of VREF/VO.
Let VO = +9V. Using the typical values of VREF/VO,
VREF is 1.223V. Choosing a value of R1 = 10 k, R2 =
63.272 k. Using the worst case VREF/VO for the
C-grade and D-grade parts, the output voltage is
actually 8.965V and 8.946V respectively. This results in
possible errors as large as 0.39% for the C-grade parts
and 0.59% for the D-grade parts. Once again, resistor
values found using the typical value of VREF/VO will
work in most cases, requiring no further adjustment.

Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Microchip received ISO/TS-16949:2009 certification for its worldwide
headquarters, design and wafer fabrication facilities in Chandler and
Tempe, Arizona; Gresham, Oregon and design centers in California
and India. The Company’s quality system processes and procedures
are for its PIC® MCUs and dsPIC® DSCs, KEELOQ® code hopping
devices, Serial EEPROMs, microperipherals, nonvolatile memory and
analog products. In addition, Microchip’s quality system for the design
and manufacture of development systems is ISO 9001:2000 certified.
