TS432I
Adjustable Precision Shunt Regulator
General Description
The TS432AI/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
TS432AI/TS432BI has a typical output impedance of 0.05Ω. Active output circuitry provides a very sharp turn-on
characteristic, making the TS432AI/TS432BI excellent replacement for zener diode in many applications.
Features

● Minimum Cathode Current for Regulation: 20µA(typ.)
● Equivalent Full Range Temp. Coefficient: 50ppm/ ºC
● Programmable Output Voltage up to 18V
● Fast Turn-On Response
● Sink Current Capability of 80µA to 100mA
● Low Dynamic Output Impedance: 0.2Ω
● Low Output Noise
