... ENABLE pin to V whenever the supply voltage is present, Noise Decoupling The NCP690 is a low noise regulator and needs no external noise reduction capacitor. Unlike other low noise regulators which require an external capacitor and have slow startup times, the NCP690 operates without a noise reduction capacitor, has a typical 50 ms turn− ...
