MIC5332

MIC5332 Micro-Power, High-Performance Dual 300mA ULDO™ General Description 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 power-on-reset (POR) generator into a 2mm x 2mm Thin MLF® 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 MLF leadless package. Data sheets and support documentation can be found on Micrel’s web site at: www.micrel.com.
