NCP4686

400 mA, High Accuracy,

Low Input Voltage, Low

Dropout Regulator

The NCP4686 is CMOS Linear voltage regulators with 400 mA

output current capability. The device has very high output voltage

accuracy, low supply current and low ON−resistance transistor. The

NCP4686 is easy to use and includes output current fold−back

protection and a fully integrated constant slope circuit as a soft−start

circuit. Due to it inrush current is minimized and no output voltage

overshoots are there. A Chip Enable function is included to save

power by lowering supply current.
