MIC5396/7/8/9 Low-Power Dual 300 m A LDO Features - 2.5V to 5.5V Input Voltage Range - Independent Power Inputs - Output Voltage Range from 1V to 3.3V - Two 300 m A Outputs - High Output Accuracy (±2%) - Low Quiescent Current (37 µA typ. per LDO) - Stable with 1 µF Ceramic Output Capacitors - Low Dropout Voltage (160 m V at 300 m A) - Independent Enable Pins - Internal Enable Pull-Down (MIC5398, MIC5399) - Output Discharge Circuit (MIC5397, MIC5399) - Thermal Shutdown Protection - Current Limit Protection - 8-Lead 1.6 mm × 1.2 mm Extra Thin DFN Package Applications - Smartphones - DSC, GPS, PMP and PDAs - Medical Devices - Portable Electronics General Description 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 m 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 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 m V at 300 m A), 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. When the MIC5397 or MIC5399 are disabled, an internal resistive load is automatically applied to the output to discharge the output capacitor. In addition, the MIC5398 and MIC5399 offer an internal enable pull-down resistor to ensure that 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. The family is available in a tiny 8-lead, 1.6 mm x 1.2 mm leadless Extra Thin DFN package.
