AMC8878/8879
LOW NOISE 150mA
LOW DROPOUT REGULATOR
DESCRIPTION
FEATURES
The AMC8878/8879 series is a low noise, low
dropout linear regulator operating from 2.5V to 6.5V
input. An external capacitor can be connected to the
bypass pin to lower the output noise level to 30µV_RMS.
Designed with a P-channel MOSFET output
transistor, the AMC8878/8879 consume a low supply
current, independent of the load current and dropout
voltage. The internal thermal shut down circuit will
limits the junction temperature to below 150°C. Other
features include thermal protection, reverse battery
protection and output current limit. Both AMC8878 and
AMC8879 come in a miniature 5-pin SOT-23 package.
