Ideally suited for powering RF and analog devices, this device can also be used to meet more general circuit needs in which a fast turnoff is essential. For battery-powered applications the low dropout and low ground current provided by the device allows the lifetime of the battery to be maximized. The Enable(/Disable) control function allows the system to further extend the battery lifetime by...
