MIC29152WU 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 | ENABLE | input | CMOS compatible control input where logic high enables the regulator and logic low shuts it down; may be tied to VIN if ON/OFF control is not required. |
| 2 | INPUT | power_in | Supplies the current to the output power device; maximum continuous operating input voltage is 26V. |
| 3 | GND | power_in | Ground pin; the TAB is also connected internally to the IC's ground. |
| 4 | OUTPUT | power_out | Regulator output voltage, with a minimum output capacitor of 10µF required for stability at full load. |
| 5 | ADJUST | input | Adjustable regulator feedback input that connects to the resistor divider from OUTPUT to GND to set the output voltage between 1.25V and 25V (reference 1.240V typ). |
| 6 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
