General Description
TS1117B are high performance positive voltage regulators are designed for use in applications requiring low
dropout performance at full rated current, Additionally, TS1117B 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. TS1117B
are three terminal regulators with fixed and adjustable voltage options available in popular packages.
Features
● Low Dropout Performance 1.5V max.
● Fill Current Rating Over Line and Temperature
● Fast Transient Response
● ±2% Total Output Regulation Over Line, Load
and Temperature
● Adjust Pin Current max 90uA Over Temperature
● Line Regulation Typical 0.015%
● Load Regulation Typical 0.05%
