The NCP583 series of low dropout regulators are designed for portable battery powered applications which require precise output voltage accuracy and low quiescent current. These devices feature an enable function which lowers current consumption significantly and are offered in two small packages; SC−82AB and the SOT−563.
A 1.0 F ceramic capacitor is the recommended value to be used with these devices on the output pin.
