TL432ACDBZT

Texas Instruments · Voltage Reference · SOT-23-3

TL432ACDBZT from Texas Instruments, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 REF input Reference / feedback input. Internally compared against the 2.495V bandgap; the device drives the CATHODE to sink whatever current is required to hold V(REF-ANODE) = Vref. Typical bias current 2µA (max 4µA at IKA = 10mA). Absolute max I_I(ref) range -0.05mA to 10mA.
2 CATHODE bidirectional Shunt current/voltage terminal. Sinks the regulated current from VKA=Vref up to 36V. Continuous IKA range -100mA to +150mA (abs max); recommended operating IKA 1mA to 100mA. Off-state leakage 0.1µA typ at VKA=36V, Vref=0.
3 ANODE power_in Common terminal, typically tied to ground/return. All voltages in the datasheet are referenced to ANODE unless noted otherwise.
