RC0431A - Low-Voltage Adjustable Precision Shunt Regulator

General Description

The RC0431A is a low-voltage 3-terminal adjustable precision voltage reference regulator.

It has an excellent thermal stability over the standard commercial temperature range.

The output voltage can be set to any value between Vref (1.24V) and 12V using two external resistors.

Key Features

  • Low voltage operation to 1.24V 1% reference voltage tolerance Output voltage adjustable from Vref to 12V Low 80µA operational cathode current 0.25Ω typical output impedance TO-92, SOT23-3 and SOT23-5 packages.

It has an excellent thermal stability over the standard commercial temperature range. The output voltage can be set to any value between Vref (1.24V) and 12V using two external resistors. The RC0431A operates from a lower voltage (1.24V) than the traditional shunt regulator references which operate from 2.5V.
