The NCP584 low dropout (LDO) linear voltage regulator is designed for portable battery powered applications which require precise output voltage accuracy, low supply current and high ripple rejection. These devices feature an enable function which lowers current consumption significantly and are offered in the SOT23-5 package. The NCP584 Series has three modes, Chip Enable (CE mode), Fast Transient Mode (FT mode) and the Low Power Mode (LP mode). Both the FT and the LP modes are controlled via the ECO pin.
