MIC5396/7/8/9 Low-Power Dual 300 mA LDO Features General Description 2.5V to 5.5V Input Voltage Range The MIC5396/7/8/9 is an advanced dual LDO ideal for powering general purpose portable devices. The Independent Power Inputs MIC5396/7/8/9 provides two high performance, Output Voltage Range from 1V to 3.3V independent 300 mA LDOs in a single package. This Two 300 mA Outputs makes it possible to improve system efficiency by High Output Accuracy (2%) providing two independent supply inputs that can be Low Quiescent Current (37 A Typ. per LDO) optimized for each individual LDO. The MIC5396/7/8/9 also features a wide output voltage range down to 1.0V. Stable with 1 F Ceramic Output Capacitors Low Dropout Voltage (160 mV at 300 mA) Its full feature set and low dropout voltage make it ideal for battery-powered applications. The MIC5396/7/8/9 Independent Enable Pins offers 2% accuracy, low dropout voltage (160 mV at Internal Enable Pull-Down (MIC5398, MIC5399) 300 mA), and low ground current (typically 42 A per Output Discharge Circuit (MIC5397, MIC5399) LDO at full load). The MIC5396/7/8/9 can also be put Thermal Shutdown Protection into a zero off mode current state, drawing virtually no Current Limit Protection current when disabled. 8-Pin 1.6 mm 1.2 mm Extra Thin DFN Package When the MIC5397/9 is disabled, an internal resistive load is automatically applied to the output to discharge Applications the output capacitor. In addition, the MIC5398/9 offers Smartphones an internal enable pull-down resistor to ensure that the DSC, GPS, PMP and PDAs output is disabled when the enable is in tri-state mode. Medical Devices These LDOs also offer fast transient response and high PSRR while consuming a minimum operating Portable Electronics current. The family is available in a tiny 8-Pin, 1.6 mm x 1.2 mm leadless Extra Thin DFN package. Package Type TDFN-8 (MT), XTDFN-8 (MX) (Top View) 2019 - 2020 Microchip Technology Inc.
