low supply current and high ripple rejection. The NCP4683 is easy to
use, with output current fold ? back protection circuit included. A Chip
Enable function is included to save power by lowering supply current.
The line and load transient responses are very good, thus this regulator
is suitable for use as a power supply for communication equipment.
