General Description
The TS1117B Series are high performance positive voltage regulators are designed for use in applications requiring low
dropout performance at full rated current, Additionally, the TS1117B 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 TS1117B Series
are three terminal regulators with fixed and adjustable voltage options available in popular packages.
This series is offered in 3-pin TO-252 SOT-223 and 8-pin SOP package.
