ATL432AIDBZR 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/feedback input pin referenced to ANODE; internally compared to 2.5V nominal reference voltage; requires minimum input current of 0.1µA for proper operation; typical input current 30-150 nA. |
| 2 | CATHODE | bidirectional | Cathode shunt regulation node; operates from 2.5V to 36V; regulates shunt current from 35µA minimum to 100mA maximum; minimum 35µA required for stable regulation per device specifications. |
| 3 | ANODE | power_in | Common anode ground reference pin; establishes voltage baseline for internal circuits and provides return path for all cathode shunt currents; typically connected to system ground. |
