AMC8878/8879
LOW NOISE 150mA
LOW DROPOUT REGULATOR
DESCRIPTION
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 30µVRMS.
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.
FEATURES
Low output noise: 30µVRMS
Industry standard’2982 pin assignment
(AMC8878)
Output voltage precision of ±1.4% accuracy
Very low dropout voltage: 50mV/50mA and
165mV/150mA
On/Off control
Low IQ: 1.6µA
Short circuit protection
Internal thermal overload protection
Available in surface mount 5-pin SOT-23 package.
Enhanced pin-to-pin Compatible to the MAX8878
(AMC8878) and TK111xxS (AMC8879) series.
