Description  
Features  
The SC1117 series of high performance positive voltage  
regulators are designed for use in applications requiring  
low dropout performance at 800mA.  
‹ 15V maximum input voltage  
‹ Low dropout performance: 1.3V max.  
‹ Full current rating over line and temperature  
‹ Fast transient response  
Additionally, the SC1117 series provides excellent  
regulation over variations in line, load and temperature.  
Outstanding features include low dropout performance  
at rated current, fast transient response, internal  
current limiting and thermal shutdown protection of the  
output device.  
‹ +2% total output regulation over line, load and  
temperature  
‹ Adjust pin current max 120µA over temperature  
‹ 5V Fixed output voltage  
‹ Line regulation 0.2% max.  
‹ Load regulation 0.4% max.  
‹ SOT-223 and TO-263 packages  
The SC1117 series of three terminal regulators offer fixed  
5V output voltage options available in both space sav-  
ing SOT-223 and TO-263 packages.  
Applications  
‹ Low voltage microcontroller supplies  
‹ Switching power supply post-regulation
