MIC39302S from HGSEMI, in a TO-263-5. 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 | EN | input | CMOS-compatible control input: logic high enables the regulator, while logic low or open puts it in shutdown. |
| 2 | IN | power_in | Supply input with a +16V maximum supply rating; the operating range is 2.25V to 16V. |
| 3 | GND | power_in | Ground pin; the ground pin and TAB are internally connected. |
| 4 | OUT | power_out | Regulator output. |
| 5 | ADJ | input | Adjustment (feedback) input that sets the output voltage through an external two-resistor divider referenced to 1.25V, with resistors up to 1MΩ. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
