MCP1702-5002E from Microchip Tech, in a TO-92. 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 that must be tied to the negative side of the output and input capacitors and to the load return, carrying only the 2.0 µA typical LDO bias current while the output regulation is referenced to this pin. |
| 2 | VIN | power_in | Unregulated input supply that requires a low source impedance for stable LDO operation, where about 1 µF of capacitance is sufficient for most applications and the input operating range is 2.7V to 13.2V. |
| 3 | VOUT | power_out | Regulated output that connects to the load and the positive terminal of the output capacitor, which should sit as close to the pin as practical, and carries the DC load current (250 mA maximum for output voltages of 2.5V or higher). |
