AMC8877
LOW NOISE 300mA
LOW DROPOUT REGULATOR
DESCRIPTION
The AMC8877 product 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 AMC8877 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. The AMC8877 come in a miniature
5-pin SOT-23 package.
FEATURES
Low output noise: 30µVRMS
Industry standard’2982 pin assignment
(AMC8877)
Output voltage precision of ±1.4% accuracy
Very low dropout voltage: 50mV/50mA,
165mV/150mA & 450mV/300mA
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
(AMC8877).
