MICROCHIP MIC5335-OOYMT-TR

The MIC5335 is a high current density, dual Ultra-Low Dropout (ULDO) linear regulator. The MIC5335 is ideally suited for portable electronics that demand overall high performance in a very small form factor. 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 HCap design that enables operation with very small output capacitors for stability, thereby reducing required board space and component cost.
