Introduction                 

      CN1117 is a series of low dropout threeterminal regulators with a dropout of 1.4V at 1A load current. CN1117 features a low standby current 2mA. Other than a fixed version (VOUT = 1.2V,1.5V, 1.8V, 2.5V,2.85V,3V, 3.3V, 3.5V, and 5.0V), CN1117 has an adjustable version, which can provide an output voltage from 1.25 to 5.0V with only two external resistors. CN1117 offers thermal shut down and current limit functions, to assure stability of chip and power system. Trimming technique is used to guarantee output voltage accuracy within 1%. Other output voltage accuracy such as 1% can be customized on demand.

      CN1117 is available in SOT-223 ,TO-220,TO-263 power packages.
