MCT1117C-3.3-TP

MCC Micro Commercial Components · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

MCT1117C-3.3-TP from MCC Micro Commercial Components, in a SOT-223. 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 ADJ/GND power_in Ground reference pin, labelled ADJ/GND on the package drawing and functioning as GND on the fixed-output MCT1117C-3.3 (the ADJ function applies only to the MCT1117C-ADJ version).
2 OUTPUT power_out Regulated 3.3V output (3.234V to 3.366V over the stated test conditions) with a maximum output current of 1.0A.
3 IN power_in Unregulated input supply; the recommended maximum input voltage is 18V and the absolute maximum input voltage is 30V, with a dropout of 1.3V at 1A.
