The NCP584 series of low drop out regulators are 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. This series of devices have three modes. Chip Enable (CE mode), Fast Transient Mode (FT mode), and Low Power Mode (LP mode). Both the FT and LP mode are utilized via the ECO pin.
