Low Dropout Regulator, Wide Input Voltage, Low Iq, 300 mA NCP718 The NCP718 is 300 mA LDO Linear Voltage Regulator. It is a very stable and accurate device with ultralow quiescent current www.onsemi.com consumption (typ. 4 A over the full temperature range) and a wide input voltage range (up to 24 V). The regulator incorporates several protection features such as Thermal Shutdown and Current Limiting.

A small capacitor is needed from this pin to ground to assure stability. 3, EXP 2 GND Power supply ground. 4 3 EN Enable pin. Driving this pin high turns on the regulator. Driving EN pin low puts the regulator into shutdown mode. 2 4 NC / ADJ Fixed Version: No connection. This pin can be tied to ground to improve thermal dissipation or left disconnected. Adjustable Version: Feedback pin for setup output voltage. Use resistor divider for voltage selection. 1 5 OUT Regulated output voltage pin. A small 1 F ceramic capacitor is needed from this pin to ground to assure stability. 5 N/C No connection. This pin can be tied to ground to improve thermal dissipation or left dis- connected.
