AMC8878/8879
LOW NOISE 150mA
LOW DROPOUT REGULATOR
ADD MICROTECH CORP.
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.
