Low Dropout Voltage 1.3V max. 
General Description
The TS1117 Series are high performance positive voltage regulators are designed for use in applications requiring low 
dropout performance at full rated current, Additionally, the PJ1117 Series provides excellent regulation over variations due 
to changes 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. The TS1117 Series are 
three terminal regulators with fixed and adjustable voltage options available in popular packages. 
This series is offered in 3-pin TO-263, TO-220, TO-252 and SOT-223 package.
