NCP4680

150 mA, Low Noise Low

Dropout Regulator

The NCP4680 is a CMOS linear voltage regulator with 150 mA

output current capability. The device is available in a tiny 0.8x0.8 mm

XDFN, and has high output voltage accuracy, low supply current and

high ripple rejection. The NCP4680 is easy to use and includes output

current fold−back protection. A Chip Enable function is included to

save power by lowering supply current. The line and load transient

responses are very good, making this regulator ideal for use as a power

supply for communication equipment.
