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
Low output noise: 30µVRMS
Industry standard’2982 pin assignment
(AMC8878)
bypass pin to lower the output noise level to 30µVRMS
.
Output voltage precision of ±1.4% accuracy
Very low dropout voltage: 50mV/50mA and
165mV/150mA
Designed with P-channel MOSFET output
a
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.
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.
