Datasheet

LMV431AIMFX/NOPB Low-Voltage Adjustable Shunt Voltage Reference IC in SOT-23-5 Package

The LMV431AIMFX/NOPB is a low-voltage, adjustable shunt voltage reference IC designed for precision regulation and voltage monitoring in compact, low-power electronic systems. Functionally similar to the classic TL431 but optimised for low-voltage operation, this device operates with a typical reference voltage of 1.24V, making it ideal for modern 3.3V and lower supply rails. Its small SOT-23-5 package supports high-density PCB designs without compromising electrical performance.

Engineered for stable operation across temperature variations, the LMV431AIMFX/NOPB delivers sharp turn-on characteristics and low dynamic impedance, allowing it to effectively replace Zener diodes in many designs. It is widely used in SMPS feedback loops, battery-powered circuits, and precision voltage regulation applications where accuracy, reliability, and space efficiency are critical.

Key Features

  • Low Reference Voltage: 1.24V typical reference for low-voltage systems
  • Adjustable Output: Programmable output voltage using external resistors
  • High Accuracy: A-grade device with tight initial tolerance
  • Low Dynamic Impedance: Provides stable regulation and fast response
  • Sharp Turn-On Characteristic: Ideal Zener diode replacement
  • Compact Package: SOT-23-5 for space-constrained designs
  • Wide Temperature Range: Suitable for industrial applications
  • Lead-Free: RoHS and NOPB compliant

Applications

  • Switching power supply feedback control
  • Battery chargers and power management circuits
  • On-board voltage regulation
  • Precision reference for analogue circuits
  • Overvoltage and undervoltage detection
