# MCP1700T-1502E

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

MCP1700T-1502E 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 pin; the datasheet's pin table lists it only as the ground connection, and the input and output capacitor grounds must return to this pin with short, wide copper. |
| 2 | VOUT | power_out | Regulated output; VOUT to GND is rated -0.3 V to 6 V (absolute maximum), and output current is limited to 600 mA typical, with a 1 uF to 22 uF output capacitor (ESR above 1 mΩ) placed close to VOUT and GND. |
| 3 | VIN | power_in | Power input; the input voltage range is 1.2 V to 5.5 V, VIN to GND is rated -0.3 V to 7 V (absolute maximum), and an input capacitor of 1 uF or larger should be placed close to VIN and GND. |
