MIC5310-2.8中文资料麦瑞半导体数据手册PDF规格书

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.
