MCP1754ST-5002E 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 LDO bias current flows out of this pin with no high current. |
| 2 | VOUT | power_out | Regulated voltage output that connects to the positive load and output capacitor, carrying the full DC load current of up to 150 mA. |
| 3 | VIN | power_in | Unregulated input supply that needs a low source impedance for stable operation, with about 1 µF of capacitance sufficient for most applications. |
