NCP718ASN300T1G

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

NCP718ASN300T1G 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 (at least 1 µF ceramic) is needed from this pin to ground to assure stability, operating input range 2.5 V to 24 V.
2 GND power_in Power supply ground.
3 EN input Enable pin; driving it high (above 1.2 V) turns on the regulator and driving it low (below 0.4 V) puts the regulator into shutdown mode.
4 NC/ADJ unconnected On this fixed 3.0 V version it is a no-connection pin that can be tied to ground to improve thermal dissipation or left disconnected (feedback pin only on the adjustable version).
5 OUT power_out Regulated output voltage pin (3.0 V for this version); a small 1 µF ceramic capacitor is needed from this pin to ground to assure stability.
