MIC29302AWD from Microchip Tech, in a TO-252-5. 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 | Enable input is active-high and TTL/CMOS-compatible, and it must not be left floating. |
| 2 | IN | power_in | Unregulated input supply, rated from +3V to +16V maximum. |
| 3 | GND | power_in | Ground pin; the TAB is also connected internally to the IC's ground on this package. |
| 4 | OUT | power_out | Regulator output voltage pin. |
| 5 | ADJ | input | Feedback input at 1.24V, set by an external resistor divider between OUT, ADJ and GND. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
