KA431SA - Programmable Shunt Regulator

Download the KA431SA datasheet PDF. This datasheet also covers the KA431S variant, as both devices belong to the same programmable shunt regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The KA431S / KA431SA / KA431SL are three

regulator series with a guaranteed thermal stability over the operating temperature range.

The output voltage can be set to any value between VREF (approximately 2.5 V) and 36 V with two external resistors.

Key Features

DATA SHEET www.onsemi.com Programmable Shunt Regulator KA431S, KA431SA, KA431SL Description The KA431S / KA431SA / KA431SL are three−terminal adjustable regulator series with a guaranteed thermal stability over the operating temperature range. The output voltage can be set to any value between VREF (approximately 2.5 V) and 36 V with two external resistors. These devices have a typical dynamic output impedance of 0.2 W. Active output circuitry provides a sharp turn−on characteristic, making these devices excellent replacement for zener diodes in many applications. Features • Programmable Output Voltage to 36 V • Low Dynamic Output Impedance 0.2 W (Typical) • Sink Current Capability: 1.
