GENERAL DESCRIPTION
The MIC5335 has an exceptional thermal performance for applications that demand higher power dissipation in a very small footprint. In addition, the MIC5335 integrates two high-performance 300 mA LDOs with independent enable functions and offers high PSRR, eliminating the need for a bypass capacitor. The MIC5335 is a µCap design that enables operation with very small output capacitors for stability, thereby reducing required board space and component cost.
