NCP114AMX280TCG

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · UDFN-4-EP(1x1)

NCP114AMX280TCG from onsemi, in a UDFN-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 small ceramic capacitor with a minimum value of 1 µF is needed from this pin to ground to assure stability.
2 GND power_in Power supply ground; the exposed pad should be connected directly to this pin.
3 EN input Driving EN above 0.9 V turns on the regulator and driving EN below 0.4 V puts it into shutdown mode.
4 IN power_in Input pin with an operating input voltage range of 1.7 V to 5.5 V; a small capacitor is needed from this pin to ground to assure stability.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
