NCP115ASN180T2G

onsemi · Linear Voltage Regulators (LDO) · TSOP-5

NCP115ASN180T2G from onsemi, in a TSOP-5. 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	IN	power_in	Input pin; a small capacitor is needed from this pin to ground to assure stability, with operating input range 1.7 V to 5.5 V.
2	GND	power_in	Power supply ground.
3	EN	input	Driving EN over 0.9 V turns on the regulator and driving it below 0.4 V puts the regulator into shutdown mode.
4	N/C	unconnected	Not connected; this pin can be tied to ground to improve thermal dissipation.
5	OUT	power_out	Regulated output voltage pin; a ceramic capacitor of minimum 1 µF is needed from this pin to ground to assure stability.
