XRP1117 800mA Low Dropout Positive Voltage Regulator May 2013 GENERAL DESCRIPTION The XRP1117 is a low power positive-voltage low dropout regulator capable of providing up to 800mA of output load current. This device is available in a fixed 3.3V output voltage and an adjustable output voltage version. The XRP1117 is optimized for low voltage operations where transient response and minimum input voltage are critical. Dropout voltage is guaranteed at a maximum of 1.3V at 800mA, decreasing at lower load currents. As the load current decreases, the quiescent current flows into the load effectively increasing the efficiency of the regulator. On chip trimming adjusts the reference/output voltage to within ± 1%.
