General Description
The MIC5331 is a tiny dual low quiescent current LDO ideal for applications that are power sensitive. The MIC5331 integrates two high performance, 300 m A LDOs into a tiny 2 mm x 2 mm Thin DFN package, which occupies less PC board area than a single SOT-23 package.
The MIC5331 is designed to reject input noise and provide low output noise with fast transient response to any load change quickly even though it is a low quiescent current part. This bination of PSRR, low noise and transient response along with low...
