MCP1825ST-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 | Connect the unregulated or regulated input supply here; the datasheet lists an input operating voltage range of 2.1V to 6.0V and recommends a 1 µF to 10 µF input capacitor for most applications, especially when the source is a battery or located far from the LDO. |
| 2 | GND | power_in | Connect to a quiet circuit ground; it carries only the quiescent current (typically 120 µA), so a heavy trace is not required, and it should return to the output capacitor return in noisy or switching-input applications. |
| 3 | VOUT | power_out | Regulated output of the LDO, which requires a minimum of 1.0 µF output capacitance for stability (ceramic, tantalum or aluminum electrolytic are all acceptable) and is rated for 500 mA output current. |
