MIC5396/7/8/9 Low-Power Dual 300m A LDO Revision 1.1 General Description The MIC5396/7/8/9 is an advanced dual LDO ideal for powering general purpose portable devices. The MIC5396/7/8/9 provides two high-performance, independent 300m A 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. The MIC5396/7/8/9 also Features 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 offers 2% accuracy, low dropout voltage (160m V at 300m A), and low ground current (typically 42μA 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. When the MIC5397/9 is disabled an internal resistive load is automatically applied to the output to discharge the output capacitor. In addition, the MIC5398/9 offers an internal enable pull-down resistor to ensure that the output is disabled when the enable is in tri-state mode. These LDO’s also offer fast transient response and high PSRR while consuming a minimum operating current. The family is available in a tiny 8-pin, 1.2mm x 1.6mm leadless Extra Thin DFN package.
