MIC5331中文资料Micro-Power High Performance Dual 300mA ULDO数据手册Microchip规格书

描述 Description

The MIC5331 is a tiny dual low quiescent current LDO ideal for applications that are power sensitive. The MIC5331 integrates two high performance, 300mA LDOs into a tiny 2mm x 2mm Thin 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 combination of PSRR, low noise and transient response along with low power consumption makes for a very high performance, yet general purpose product.The MIC5331 is a µCap design, operating with very small ceramic output capacitors, which reduces required board space and component cost; and it is available in fixed output voltages in the tiny 8-pin 2mm x 2mm Thin leadless package.
