General Description
TS1085 are high performance positive voltage regulators are designed for use in applications requiring low dropout
performance at full rated current, Additionally, TS1085 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. TS1085 are three terminal
regulators with fixed and adjustable voltage options available in popular packages.
Features
