NCP584
Tri鈭扢ode 200 mA CMOS
LDO Regulator with Enable
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鈭? 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.
