MCP1755T-3302E

Microchip Tech · Power Management - Specialized · SOT-23-5

MCP1755T-3302E from Microchip Tech, in a SOT-23-5. 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 VIN power_in Unregulated supply input, specified from 3.6V to 16.0V; low source impedance is needed for stable operation, and about 1 µF of capacitance is sufficient for most applications.
2 GND power_in Regulator ground that is tied to the negative side of the input and output capacitors and carries only the LDO bias current, with voltage drops to the load minimized.
3 SHDN input Shutdown input where a logic-high enables the LDO output and a logic-low disables it, also driving PWRGD low and placing the LDO in a low quiescent current shutdown state.
4 PWRGD output Open-drain power good output that goes active when VOUT is within 92% (typical) of nominal, with 2% typical hysteresis and a 100 µs (typical) power-up delay, and may be pulled up to VIN or VOUT.
5 VOUT power_out Regulated voltage output that connects to the load and the positive side of the output capacitor, which should be placed as close to this pin as practical, and carries the DC load current.
