General Description

The TS432/432A/432B is a three-terminal adjustable shunt regulator with specified thermal stability. The output voltage may be set to any value between Vref (approximately 1.24V) and 18V with two external resistors. The TS432/432A/432B has a typical output impedance of 0.2Ω. Active output circuitry provides a very sharp turn-on characteristic, making the TS432/432A/432B excellent replacement for zener diode in many applications. This series is offered in 3-pin TO-92, SOT-89, SOT-23 and 5-pin SOT-25 package.
