MCP1701AT-3002I from Microchip Tech, in a SOT-23A-3. 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 | GND | power_in | Regulator ground; tie to the negative side of the output and input capacitors, and only the 2 µA typical LDO bias current flows out of this pin. |
| 2 | VOUT | power_out | Regulated voltage output that carries the DC load current; the output capacitor's positive terminal should be placed as close as possible to this pin. |
| 3 | VIN | power_in | Unregulated supply input carrying the DC load current plus 2 µA typical bias current; the input capacitor should be located as close as possible to this pin, and the input voltage is specified up to 10 V. |
