PJ9500M25SA

PJSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

PJ9500M25SA from PJSEMI, 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 GND power_in Ground pin for the regulator; the datasheet gives no separate electrical limit for it, and the input and output capacitors should be placed close to the VIN/GND and OUT/GND pins.
2 VOUT power_out Regulated output of the LDO, rated for up to 500 mA load current with the VOUT-to-VIN voltage limited to -0.3 V to 5 V.
3 VIN power_in Power input with an operating supply range of 1.8 V to 6 V and an absolute maximum VIN voltage of -0.3 V to 6 V to GND.
