MIC5270-3.0YM5-TR from Microchip Tech, in a SOT-23-5. 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 | NC | unconnected | Not internally connected (fixed-output -3.0V version). |
| 2 | GND | power_in | Ground. |
| 3 | NC | unconnected | Not internally connected (fixed-output version; pin 3 is ADJ only on the adjustable part). |
| 4 | -OUT | power_out | Negative regulator output, fixed -3.0V with ±2% initial accuracy and up to 100mA output current. |
| 5 | -IN | power_in | Negative supply input, operating range -16V to -3.3V (absolute maximum -20V to +0.3V). |
