General Description
The TS1085 Series are high performance positive voltage regulators are designed for use in applications requiring low
dropout performance at full rated current, additionally, the PJ1085 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 TS1085 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 and TO-252 package.
