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
