CJ6336-M3N-5.0 from Changjing, in a SOT-23-3L. 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; place the input and output capacitors as close as possible between this pin and IN/OUT. |
| 2 | OUT | power_out | Regulated fixed 5.0V output (±2% at 25°C) delivering up to 200mA, with a recommended 10µF capacitor to GND and absolute maximum of 26V. |
| 3 | IN | power_in | Supply input accepting 2.5V to 26V (absolute maximum 30V), with a recommended 10µF capacitor to GND. |
