NCP170AMX180TCG

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

NCP170AMX180TCG 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 pin; connect a ceramic output capacitor of 1.0 µF or greater (up to 10 µF) as close as possible to this pin.
2 GND power_in Power supply ground.
3 EN input Chip enable, active high: below 0.4 V the device is disabled (and output discharged on the A option), above 1.2 V it is enabled; tie to IN if unused.
4 IN power_in Power supply input voltage, operating range 2.2 V to 5.5 V, with at least a 1 µF ceramic capacitor to GND recommended.
5 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
