# MCP1700T-1802E

**MSKSEMI** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

MCP1700T-1802E from MSKSEMI, in a SOT-23. 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 | Ground connection; the input and output capacitor ground connections must be returned to this pin using short, wide copper traces. |
| 2 | VOUT | power_out | Regulated voltage output; an output capacitor of 1uF to 22uF with ESR above 1mΩ should be placed close to the VOUT and GND pins, and the device limits output current to 600mA typical under short-circuit. |
| 3 | VIN | power_in | Power input with an operating range of 1.2V to 5.5V (absolute maximum VIN to GND is -0.3V to 7V); a 1uF or larger input capacitor should be placed close to the VIN and GND pins. |
