Microchip Technology MIC5396
The MIC5396, MIC5397, MIC5398, and MIC5399 are advanced dual LDOs ideal for powering general purpose portable devices. The MIC5396/7/8/9 provide two high performance, independent 300 mA LDOs in a single package. This makes it possible to improve system efficiency by providing two independent supply inputs that can be optimized for each individual LDO.FEATURES

GENERAL DESCRIPTION
The MIC5396/7/8/9 also feature a wide output voltage range down to 1.0V. Its full feature set and low dropout voltage make it ideal for battery-powered applications. The MIC5396/7/8/9 offer 2% accuracy, low dropout voltage (160 mV at 300 mA), and low ground current (typically 42 µA per LDO at full load). The MIC5396/7/8/9 can also be put into a zero off mode current state, drawing virtually no current when disabled.
