The LM1117GS-3.3 is a 3.3V low dropout regulator (LDO) SOT-223-3LRoHS manufactured by HTC Korea. It is a small packages power management solution ideal for portable devices. It provides precise output voltage regulation, extremely low dropout voltage, and high-current output which makes it suitable for data switch or logic regulator applications that require a small and reliable solution. The LM1117GS-3.3 is rated to have an output current up to 1.5A which makes it suitable for high power applications. It also has an enable function allowing the logic to turn on/off the output voltage. It features an internal over temperature protection and current limit protection as safety measures that prevent any problems with the output from occurring.
