The RS1117 is a linear voltage regulator which has the advantage of low noise, highly accurate and low power. The RS1117 allow an input voltage as high as 18V and contains six output voltages of 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, 5V to support a wide variety of applications. Additionally, the RS1117 has internal protection features containing thermal shutdown and foldback current limit that limits the power dissipation of device during high load current faults and shorting events.
