ISL70005SEH Overview
Datasheet ISL70005SEH, ISL73005SEH Radiation Hardened Dual Output 3A Synchronous Buck and ±1A LDO Regulator for DDR VDDQ and VTT The ISL70005SEH and ISL73005SEH are radiation hardened dual output Point-of-Load (POL) regulators bining the high efficiency of a synchronous buck regulator with the low noise of a Low Dropout (LDO) regulator. They are suited for systems with 3.3V or 5V power buses and can support...
