Voltage Reference datasheet and documents for LM4041C12QDBZR

LM4041C12QDBZR

Voltage Reference Overview

The LM4041C12QDBZR is a precision micropower shunt voltage reference from Texas Instruments, featuring a fixed nominal output of 1.23V with an initial accuracy of ±0.5%. It operates within a wide current range of 60µA to 12mA and exhibits a temperature coefficient of 100ppm/°C. The device supports a maximum series input voltage of 10V and functions reliably across an extended industrial temperature range of -40°C to +125°C. Packaged in a compact SOT-23-3 surface-mount format, it ensures stability with any capacitive load without requiring external compensation components.

Voltage Reference Feature Summary

Provides stable reference voltage across wide operating currents and temperatures
Capable of driving all capacitive loads without external output capacitors
Utilizes Zener-zap trimming for precise initial accuracy and low temperature drift

Voltage Reference Applications

Data acquisition systems
Power supply monitoring circuits
Precision audio equipment
Automotive electronics
Battery-powered devices

Voltage Reference Procurement Notes

Verify the specific suffix 'Q' indicates automotive qualification status and 'R' denotes reel packaging configuration. Confirm that the C grade corresponds to the documented ±0.5% accuracy and 100ppm/°C temperature coefficient specifications. Ensure the ordering part number matches the required SOT-23-3 package and extended temperature range requirements for the target application environment.

Voltage Reference Selection Notes

Select this component when a fixed 1.23V reference is required with high precision in space-constrained designs. It is suitable for applications demanding stability under varying load conditions without additional output filtering. Consider the extended temperature range and automotive qualification if the environment exceeds standard industrial limits or requires robust reliability standards.

Voltage Reference Part Context

This part belongs to the LM4041 family of precision micropower shunt references. It offers adjustable outputs via external resistors or fixed options like 1.225V. The family includes various grades (A, B, C, D) with differing accuracies and temperature coefficients, packaged in SC-70, SOT-23, and TO-92 formats to suit diverse mounting and performance needs.
