PJ9400L33SC from PJSEMI, in a SOT-23-3. 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 | GND | power_in | Ground reference pin for the regulator; the input decoupling capacitor and output capacitor must be placed close to the device VIN, OUT and GND pins. |
| 2 | VOUT | power_out | Regulated output voltage, rated for up to 400mA (Maximum Output Current 400mA, Maximum Load Current 450mA absolute maximum) and requires a 1uF to 10uF output capacitor with ESR of 5mΩ to 500mΩ. |
| 3 | VIN | power_in | Power input voltage, with a recommended supply range of 1.5V to 8V (absolute maximum -0.3V to +9V) and a 1uF ceramic input capacitor recommended to GND. |
