... General Description The MIC5310 is a tiny Dual Ultra Low-Dropout (ULDO™) linear regulator ideally suited for portable electronics due to its high power supply ripple rejection (PSRR) and ultra low output noise. The MIC5310 integrates two high-performance; 150mA ULDOs into a tiny 2mm x 2mm leadless MLF package, which provides exceptional thermal package characteristics ...

... PSRR. Turn-on time increases slightly with respect to bypass capacitance. A unique, quick-start circuit allows the MIC5310 to drive a large capacitor on the bypass pin without significantly slowing turn-on time. No-Load Stability Unlike many other voltage regulators, the MIC5310 will remain stable and in regulation with no load ...
