MIC29301-5.0WU-TR from Microchip Tech, 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 and logic-low shuts it down, and the EN input may be directly tied to 30V or below. |
| 2 | IN | power_in | Supplies the current to the output power device. |
| 3 | GND | power_in | Ground pin; the TAB is also connected internally to the IC's ground. |
| 4 | OUT | power_out | The regulator output voltage. |
| 5 | FLG | output | Active-low open-collector error flag output that pulls low to indicate an output fault condition and may sink 10 mA. |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
