MCP1703A-5002E from Microchip Tech, in a SOT-223-3. 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 | VIN | power_in | Unregulated input supply; connect to the input source, which needs low source impedance, and about 1 µF of capacitance ensures stable operation in most applications, with an input operating range of 2.7V to 16.0V. |
| 2 | GND | power_in | Regulator ground, tied to the negative side of the output and input capacitors; only the 2.0 µA typical LDO bias current flows out of this pin, and the tab is internally connected to this pin. |
| 3 | VOUT | power_out | Regulated output voltage that carries the full DC load current and should be connected to the load and the positive terminal of the output capacitor, which is stable with 1.0 µF to 22 µF ceramic capacitance. |
