TL432LIACDBZR

Texas Instruments · Voltage Reference · SOT-23-3

TL432LIACDBZR from Texas Instruments, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 REF input Reference input pin; voltage internally regulated to 2.495V nominal (±1% A-grade or ±0.5% B-grade) relative to anode; accepts -5 to +10mA input current (absolute maximum); requires minimum 0.4µA from external resistor divider feedback network.
2 CATHODE bidirectional Cathode output pin; programmable shunt regulator output from 2.495V to 36V via external resistor divider feedback; supports 1-15mA continuous sink current, absolute maximum 18mA; 0.3Ω typical output impedance.
3 ANODE power_in Common anode pin; system ground reference for all voltage measurements; substrate current return path.
