NCP114ASN300T1G

onsemi · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · TSOP-5

NCP114ASN300T1G 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, and the operating input voltage range is 1.7 V to 5.5 V.
2 GND power_in Power supply ground.
3 EN input Driving EN above 0.9 V turns on the regulator, and driving EN 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 small ceramic capacitor with a minimum value of 1 µF is needed from this pin to ground to assure stability.
