MIC5335中文资料Dual, High Performance 300mA uCap ULDO数据手册Microchip规格书

描述 Description

The MIC5335 is a high current density, dual Ultra Low Dropout (ULDO) linear regulator. The MIC5335 is ideally suited for portable electronics which demand overall high performance in a very small form factor. The MIC5335 delivers exceptional thermal performances for those applications that demand higher power dissipation requirements in a very small footprint. In addition, the MIC5335 integrates two high performance 300mA LDOs with independent enable functions and offers high PSRR eliminating the need for a bypass capacitor. The MIC5335 is a µCap design which enables operation with very small output capacitors for stability, thereby reducing required board space and component cost. The MIC5335 is available in fixed output voltages. Additional voltages are available. For more information, contact Microchip sales office.
