| TECHNICAL DATA Features Adjustable and Fixed of 1.8V, 2.5V, 3.3V, 5.0V Space saving SMD types of SOT-223 Output Current up to 1A Low Dropout Voltage ( 700mV at 1A Output Current ) Very Low Quiescent Current Internal Current and Terminal Limit Output trimmed to 2% Tolerance 0.04% Line Regulation, 0.1% Load Regulation General Description The SE1117 is a low power positive-voltage regulator designed to meet 1A of output current. The SE1117 features very low quiescent current and very low dropout voltage of 700mV at a full load and lower as output current decreases. The SE1117 is available in four fixed voltages, 1.8V, 2.5V, 3.3V and 5.0V. Additonally it is also available in adjustable version. The SE1117 series is offered in a 3-pin SOT-223 packages. A minimum of 10uF capacitor is required at the output to improve the transient response and stability.
