ATL432LIAQDBZRQ1

Texas Instruments · Voltage Reference · SOT-23-3

ATL432LIAQDBZRQ1 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 voltage input to internal comparator; device regulates when this voltage equals internal 2.5 V threshold with maximum required bias current of 0.4 µA.
2 CATHODE bidirectional Regulated output and shunt current sink node; supports output voltage range from 2.5 V to 36 V with continuous sink current capability from 0.08 mA to 15 mA.
3 ANODE power_in Ground/common reference pin; return path for all internal and output sink currents.
