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. |
