MCP1754ST-5002E

Microchip Tech · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23A-3

MCP1754ST-5002E from Microchip Tech, in a SOT-23A-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, and only the LDO bias current flows out of this pin with no high current.
2 VOUT power_out Regulated voltage output that connects to the positive load and output capacitor, carrying the full DC load current of up to 150 mA.
3 VIN power_in Unregulated input supply that needs a low source impedance for stable operation, with about 1 µF of capacitance sufficient for most applications.
