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.
