General Description
The TS432I/432AI/TS432BI 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
TS432I/432AI/TS432BI has a typical output impedance of 0.05Ω. Active output circuitry provides a very sharp turn-on
characteristic, making the TS432I/432AI/TS432BI excellent replacement for zener diode in many applications.
