NCP718BSN500T1G

onsemi · Linear Voltage Regulators (LDO) · TSOT-23-5

NCP718BSN500T1G from onsemi, in a TSOT-23-5. 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.
2 GND power_in Power supply ground.
3 EN input Enable pin; driving this pin high turns on the regulator and driving it low puts the regulator into shutdown mode.
4 NC/ADJ unconnected Fixed version: no connection, can be tied to ground to improve thermal dissipation or left disconnected.
5 OUT power_out Regulated output voltage pin; a small 1 µF ceramic capacitor is needed from this pin to ground to assure stability.
