PJ73AL36SQ

PJSEMI · Linear Voltage Regulators (LDO) · SOT-89

PJ73AL36SQ from PJSEMI, in a SOT-89. 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 GND power_in Ground reference for the regulator.
2 VIN power_in Input supply, rated up to 20V in operation (absolute maximum -0.3 to +22V).
3 VOUT power_out Regulated 3.6V output (±2%) delivering at least 300mA, with 400mA typical short-circuit current.
