General Description
The MIC5330 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 MIC5330 integrates two high performance 300mA ULDOs into a tiny 2mm x 2mm leadless MLF® package, which provides exceptional thermal package characteristics.
