L-MCP1700T-2802E

PIELENST · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

L-MCP1700T-2802E from PIELENST, in a SOT-23-3. 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 GND power_in Ground reference pin; the datasheet pin table gives its function only as ground (接地).
2 VOUT power_out Regulated voltage output, with fixed options of 1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.0V and 3.3V and an output current capability of 300mA.
3 VIN power_in Power input pin, with an input voltage range of 1.2V to 5.5V per the electrical characteristics table.
