NCP4682: Linear Voltage Regulator, LDO, Ultra Low Iq, 150 mA

Product Description
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 µA (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.
