ATL432LIAIDBZR

Texas Instruments · Voltage Reference · SOT-23-3

ATL432LIAIDBZR 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 to internal error amplifier; requires 0.4µA maximum bias current and maintains 2.5V ±1% nominal threshold voltage relative to ANODE
2 CATHODE bidirectional Regulated output node; sources voltage from 2.5V to 36V and sinks programmable current from 0.1mA to 15mA maximum based on external resistive feedback network
3 ANODE power_in Common ground return; provides reference potential for internal comparator and current source return path
