LM4040/LM4041
Precision Micropower Shunt Voltage
Reference
General Description
Ideal for space critical applications, the LM4040 and
LM4041 precision voltage references are available in the
subminiature (3mm × 1.3mm) 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 60μA for the
LM4041-1.2 to 74μA for the LM4040-5.0. LM4040 versions
have a maximum operating current of 15mA. LM4041
versions have a maximum operating current of 12mA.
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.
Datasheets and support documentation are available on
Micrel’s web site at: www.micrel.com.

Notes:
1. Exceeding the absolute maximum ratings may damage the device.
2. The device is not guaranteed to function outside its operating ratings.
3. The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX (maximum junction temperature), ƟJA (junction
to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDMAX = (TJMAX
TA)/ ƟJA 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.
4. Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5kin series with 100pF. The machine model is a
200pF capacitor discharged directly into each pin.
5. Specification for packaged product only.
6. The boldface (overtemperature) limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown Voltage
Tolerance ±[(ΔVR/ΔT)(65°C)(VR)]. ΔVR/ΔT is the VR temperature coefficient, 65°C is the temperature range from 40°C to the reference point of
25°C, and VR is the reverse breakdown voltage. The total overtemperature tolerance for the different grades follows:
a. C-grade: ±1.15% = ±0.5% ±100ppm/°C × 65°C
b. D-grade: ±1.98% = ±1.0% ±150ppm/°C × 65°C
Example: The C-grade LM4040-2.5 has an overtemperature Reverse Breakdown Voltage tolerance of ±2.5 × 1.15% = ±29mV.
