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.
