The IP1117 is available in four fixed voltages, able in adjustable version. On chip precision trimming adjusts the reference/output voltage to within ±2%. Current limit is also trimmed to ensure specified out- put current and controlled short-circuit current The IP1117 series is available in SOT-223 power packages. - Adjustable and Fixed of 1.8V, 2.5V, 3.3V,5.0V - Space saving SMD types of SOT-223 - 1.0A Output Current capability - 1.1V drop-out voltage - Foldback current limiting - Thermal protection - Over current protection
