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 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.
FEATURES
Low output noise: 30µV_RMS
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 I_Q: 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.
