NCP4682, NCP4685
150 mA, Ultra Low Supply
Current, Low Dropout
Regulator
The NCP4682 and NCP4685 are CMOS Low Dropout Linear
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 foldback 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.
Features
