US431AL - LOW -VOLTAGE ADJUSTABLE PRECISION SHUNT REGULATOR

This page provides the datasheet information for the US431AL, a member of the US431L LOW -VOLTAGE ADJUSTABLE PRECISION SHUNT REGULATOR family.

Description

The US431L product is a 3 terminal adjustable shunt regulator that can also be used as a precision voltage reference.

Its output voltage may be set to any value between Vref(1.24V) and 6V with two external resistors as shown in the typical application circuit.

Features

  • SOT23-5 package 0.5% Voltage Reference Initial Accuracy (US431AL) Low Operational Cathode Current (80 uA max) Unconditionally Stable with only 1uF Adjustable Output from 1.24V to 6V 0.25Ω Typical Output Impedance Pin to Pin Compatible with TLV431.
