MCP1700-3002E

Microchip Tech · IC · TO-92-3

MCP1700-3002E from Microchip Tech, in a TO-92-3. 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 Regulator ground; tie to the negative side of the output and input capacitors, only the 1.6 µA typical LDO bias current flows out of this pin and output regulation is referenced to it.
2 VIN power_in Unregulated supply voltage input (2.3V to 6.0V operating range); connect to the input source with about 1 µF of capacitance for stable operation.
3 VOUT power_out Regulated voltage output; connect to the positive side of the load and output capacitor, and the current flowing out equals the DC load current (up to 250 mA for VOUT ≥ 2.5V).
