DESCRIPTION AMC8878/8879 LOW NOISE 150mA LOW DROPOUT REGULATOR 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 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. 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.
