LMV431A Datasheet Low-voltage (1.24v) Adjustable Precision Shunt Regulators

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LMV431/LMV431A/LMV431B Low-Voltage (1.24V) Adjustable Precision Shunt Regulators August 2003 LMV431/LMV431A/LMV431B Low-Voltage (1.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LMV431, LMV431A and LMV431B are precision 1.24V shunt regulators capable of adjustment to 30V.

Negative feedback from the cathode to the adjust pin controls the cathode voltage, much like a non-inverting op amp configuration (Refer to Symbol and Functional diagrams).

A two resistor voltage divider terminated at the adjust pin controls the gain of a 1.24V band-gap reference.

Key Features

  • n Low Voltage Operation/Wide Adjust Range (1.24V/30V) n 0.5% Initial Tolerance (LMV431B) n Temperature Compensated for Industrial Temperature Range (39 PPM/˚C for the LMV431AI) n Low Operation Current (55µA) n Low Output Impedance (0.25Ω) n Fast Turn-On Response n Low Cost.
