Microchip Technology MIC5399-GMYMX-T5

Description
The MIC5396/7/8/9 is a dual LDO ideal for powering portable devices. It provides two independent 300mA LDOs in a single package, allowing for improved system efficiency. The MIC5396/7/8/9 has a wide output voltage range down to 1.0V, making it suitable for battery-powered applications. It offers 2% accuracy, low dropout voltage (160mV at 300mA), and low ground current (42μA per LDO at full load). The MIC5396/7/8/9 can be put into a zero off mode current state, drawing virtually no current when disabled. The MIC5397/9 has an internal resistive load to discharge the output capacitor when disabled, while the MIC5398/9 has an internal enable pull-down resistor to ensure the output is disabled when the enable is in tri-state mode. These LDOs also offer fast transient response and high PSRR while consuming a minimum operating current. They are available in an 8-pin, 1.2mm x 1.6mm Extra Thin DFN package.
