Description

The SE1117-1.8 is an electronic component model classified under IC chips product category. It 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. It is available in four fixed voltages, 1.8V, 2.5V, 3.3V and 5.0V, and an adjustable version in space saving SMD types of SOT-223. A minimum of 10uF capacitor is required at the output to improve the transient response and stability. The output is trimmed to ±2% tolerance and has 0.04% Line Regulation and 0.1% Load Regulation.
