Device Overview

Summary

The MIC5332 is a tiny dual low quiescent current LDO ideal for applications that are power sensitive. The MIC5332 integrates two high performance 300mA LDOs and a POR generator into a 2mm x 2mm Thin package. This solution occupies the same PC board area of a single SOT-23 package.

The MIC5332 is designed to reject input noise and provide low output noise with fast transient response so as to respond 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 MIC5332 is a µCap design, operating with very small ceramic output capacitors, which reduces required board space and component cost. It is available in fixed output voltages in a tiny 8-pin 2mm x 2mm Thin leadless package.
