NCP115CMX280TCG

onsemi · Linear Voltage Regulators (LDO) · XDFN-4-EP(1x1)

NCP115CMX280TCG from onsemi, in a XDFN-4-EP(1x1). 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 OUT power_out Regulated output voltage pin; a ceramic capacitor of at least 1 µF is needed from this pin to ground to assure stability.
2 GND power_in Power supply ground.
3 EN input Driving EN over 0.9 V turns on the regulator; driving EN below 0.4 V puts the regulator into shutdown mode.
4 IN power_in Input pin (1.7 V to 5.5 V operating range); a small capacitor is needed from this pin to ground to assure stability.
5 EPAD passive Exposed pad should be connected directly to the GND pin and soldered to a large ground copper plane for effective heat removal.
