NCP583
Ultra-Low Iq 150 mA CMOS
LDO Regulator with Enable
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
mF
ceramic capacitor is the recommended value to be used
with these devices on the output pin.
