NCP167AMX280TBG

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

NCP167AMX280TBG 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; the output should be bypassed with a small 1 µF ceramic capacitor.
2 GND power_in Common ground connection.
3 EN input Chip enable: VEN < 0.4 V disables the regulator, VEN > 1.2 V enables the LDO.
4 IN power_in Input voltage supply pin, operating range 1.9 V to 5.5 V.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
