MIC5356-MGYML-T5 Microchip

MIC5355/6 Dual 500mA Cap Low Dropout, Micropower Linear Regulator General Description Features The MIC5355/6 is an advanced dual, micropower, low 2.5V to 5.5V input voltage range dropout linear regulator. The MIC5355/6 provides low 2% initial output accuracy quiescent current operation, using only 70 A with both Wide output voltage range: 1.0V to 3.3V outputs enabled making it ideal for battery-powered Low quiescent current: 38A per output systems. In shutdown, the quiescent current drops to less than 1A. The MIC5355/6 provides two independently- Very low quiescent current in shutdown: <1 A typical controlled high-performance 500mA LDOs with typical Cap stable with 2.2F ceramic capacitor dropout voltage of 350mV at rated load. In addition, the Low dropout voltage: 350mV at 500mA MIC5355/6 is optimized to provide fast load and line Excellent load/line transient response transient performance with low-ESR ceramic output Independent logic controlled enable pins capacitors, requiring a minimum of only 2.2F. Output discharge circuit: MIC5356 The MIC5356 also incorporates an active discharge feature when the part is disabled that switches in a 30 Current and thermal limit protection load to pull down the output of the regulator. The Power 8-pin ePad MSOP package or 8-pin ePad 3mm MIC5355/6 is available in fixed output voltages in a x 3mm MLF package thermally-enhanced 8-pin ePad MSOP package or 8-pin ePad 3mm x 3mm MLF package.
