SOT-23 Pin Definition: 1. Reference 2. Cathode 3. Anode 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.
