Datasheet

LM431BIM3X/NOPB Adjustable Shunt Voltage Reference IC 2.5V–36V in SOT-23-3 Package

The LM431BIM3X/NOPB is a precision adjustable shunt voltage reference IC designed to provide stable and accurate voltage regulation in compact analogue and power management circuits. Functionally compatible with the TL431 family, this device offers improved performance with tight initial accuracy and excellent thermal stability. The output voltage can be programmed from 2.5V up to 36V using two external resistors, making it highly versatile across a wide range of applications.

Housed in a SOT-23-3 surface-mount package, the LM431BIM3X/NOPB is well suited for space-constrained PCB designs. Its sharp turn-on characteristics and low dynamic impedance allow it to effectively replace Zener diodes in feedback, regulation, and monitoring circuits. With reliable operation across industrial temperature ranges, it is commonly used in SMPS control loops, battery chargers, and on-board voltage regulation.

Key Features

  • Adjustable output voltage: Programmable from 2.5V to 36V using external resistors
  • High accuracy B-grade: Tight initial voltage tolerance for precision regulation
  • Low dynamic impedance: Ensures stable regulation over varying load conditions
  • Sharp turn-on response: Ideal replacement for conventional Zener diodes
  • Compact SMD package: SOT-23-3 for high-density PCB layouts
  • Wide operating temperature: Suitable for industrial environments
  • Lead-free compliance: RoHS and NOPB compliant
