NCP115ASN120T2G

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

NCP115ASN120T2G 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 of the regulator, operating input voltage range 1.7 V to 5.5 V, with a small capacitor required from this pin to ground for stability.
2 GND power_in Power supply ground pin.
3 EN input Driving EN above 0.9 V turns on the regulator and driving it below 0.4 V puts it into shutdown mode, with an internal pull-down of typ. 300 nA that keeps the device off when EN is not connected.
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, requiring a small ceramic capacitor with a minimum value of 1 µF from this pin to ground to assure stability.
