LM431AIMX/NOPB

Voltage Reference Overview

The LM431AIMX/NOPB is an adjustable precision Zener shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495 V to 37 V with an initial accuracy of ±2.2%. The device features a temperature coefficient of 50 PPM/°C and supports a maximum shunt current of 100 mA. It is housed in an 8-SOIC package and functions within a temperature range of -40°C to +85°C.

Voltage Reference Feature Summary

Provides adjustable reference voltage functionality via external resistor divider
Delivers high precision regulation with low temperature drift characteristics
Supports high cathode current capacity for robust load handling

Voltage Reference Applications

Precision voltage references in power supply circuits
Programmable linear regulators
Battery-operated equipment requiring stable reference voltages

Voltage Reference Procurement Notes

Verify the specific suffix 'NOPB' confirms RoHS compliance and lead-free construction as per manufacturer specifications. Confirm the 8-SOIC package type matches your PCB footprint requirements. Ensure the ±2.2% initial accuracy meets your circuit tolerance needs before finalizing procurement decisions.

Voltage Reference Selection Notes

Select this component when a surface-mount adjustable shunt regulator is required with moderate precision. The 8-SOIC package offers a compact solution compared to through-hole alternatives. Consider the 100 mA current limit for load requirements and verify thermal performance within the specified operating temperature range.

Voltage Reference Part Context

This part belongs to the LM431 family of adjustable precision Zener diodes from Texas Instruments. It serves as a direct replacement for standard Zener diodes in applications requiring higher accuracy and lower temperature coefficients. The device integrates a bandgap reference and error amplifier on a single monolithic IC structure.
