AP431SHARTR-G1

Diodes Incorporated · Voltage Reference · SOT-89-3

AP431SHARTR-G1 from Diodes Incorporated, in a SOT-89-3. 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 that sets the output voltage via a resistor divider, with VREF of 2.495V (AP431SH) and a reference input current range up to 10mA absolute maximum.
2 ANODE power_in Anode terminal, normally connected to ground, with a cathode current range of -100 to 150mA absolute maximum.
3 CATHODE passive Cathode terminal that sinks 0.1mA to 100mA of current, with a cathode voltage from VREF up to 36V (40V absolute maximum).
