NCP4682, NCP4685

150 mA, Ultra Low Supply

Current, Low Dropout

Regulator

voltage regulators with 150 mA output current capability. The devices

have high output voltage accuracy, a 1 mA (typ.) ultra low supply

current and high ripple rejection. Current fold−back protection is

integrated in the devices to protect against over current and short

current conditions. A Chip Enable (NCP4682 only) function is

included to save power by further lowering supply current, which is

advantageous for battery powered applications. The NCP4685 is

optimized for the lowest quiescent current possible in applications

where the device is always on.
