MCP1799T-5002H

Microchip Tech · Power Management - Specialized · SOT-23

MCP1799T-5002H from Microchip Tech, 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 that should be tied to an electrically quiet circuit ground for optimal noise and PSRR performance, and returned to the output capacitor return on noisy inputs.
2 VOUT power_out Regulated output voltage VR (3.3 V or 5.0 V versions) that requires a minimum of 1 µF ceramic output capacitance for stability.
3 VIN power_in Input voltage supply with an operating input range of 4.5 V to 45 V, where a 1 µF to 10 µF ceramic input capacitor is recommended for most applications.
