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 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%
● Adjustable Output Voltage

Note 1: See thermal regulation specification for changes in output voltage due to heating effects. Line and load
regulation are measured at a constant junction temperature by low duty cycle pulse testing. Load
regulation is measured at the output lead = 1/18” from the package.
Note 2: Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation
is determined by the input / output voltage difference and the output current. Guaranteed maximum power
dissipation will not be available over the full input / output voltage range.
Note 3: Quiescent current is defined as the minimum output current required to maintain the regulation.
Note 4: The Output Capacitor does not have a theoretical upper limit and increasing its value will increase stability
