PJ9193BM33SE

PJSEMI · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5

PJ9193BM33SE from PJSEMI, in a SOT-23-5. 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 VIN power_in Power input voltage; the recommended supply range is 2.0 V to 6.0 V, and the absolute maximum VIN is -0.3 V to +6.5 V.
2 GND power_in Ground reference pin for the regulator; the input and output capacitors should be connected between VIN/OUT and GND, with wide copper traces on VIN and GND.
3 EN input Chip enable, active high: the regulator turns on when EN is pulled high (VIH min 1.5 V) and shuts down when pulled low (VIL max 0.3 V); the pin is high impedance and has an internal 1 MΩ typical pull-down.
4 NC unconnected No internal connection.
5 VOUT power_out Regulated output voltage; the datasheet specifies 0 to 300 mA recommended output current (500 mA maximum load current), with a 1 µF to 2.2 µF ceramic output capacitor and 5 mΩ to 100 mΩ ESR recommended.
