MCP1824ST-3302E 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 | Input voltage supply with an operating range of 2.1V to 6.0V, where a 1 µF to 10 µF input capacitor is recommended for battery or remote sources. |
| 2 | GND | power_in | Ground pin that should be tied to a quiet circuit ground and carries only the LDO ground current. |
| 3 | VOUT | power_out | Regulated output voltage that requires a minimum of 1.0 µF output capacitance for stability. |
