The LM1117MPX-1.8 by Texas Instruments is a low dropout (LDO) positive fixed voltage regulator with an operating input voltage range of 2.5V to 15V and an output voltage of 1.2V. It is capable of delivering 800mA of output current, and comes in a SOT-223 package. It is RoHS compliant, which means that it is free from hazardous substances. This LDO regulator is suitable for applications that require only a very low dropout voltage and a very low quiescent current.
