General Description

The AP432/432A are 3-terminal adjustable precision shunt regulators with guaranteed stable temperature over the applicable extended commercial temperature range. The output voltage may be set at any level greater than 1.24/ (VREF) up to 20V merely by selecting two external resistors that act as a voltage divider network.
