AiP431GA23.TR

Wuxi I-core Elec · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

AiP431GA23.TR from Wuxi I-core Elec, in a SOT-23. 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 Cathode passive Cathode is the shunt current path of the reference, rated at a maximum cathode-anode voltage of 37 V (36 V recommended operating) and a cathode current of 1 mA to 100 mA in regulation, with an absolute maximum of 150 mA.
2 Ref input Ref is the reference input that sets the output voltage through an external divider, with a reference voltage of about 2.495 V and a reference input current of 2 µA typical (4 µA max), and an absolute maximum reference input current of 10 mA.
3 Anode passive Anode is the common terminal of the shunt reference; the datasheet states no separate electrical limit for this pin beyond the cathode-anode ratings.
