General Description
TS1085 are high per formance positive voltage regulators are designed for use in applications r equiring low dropout perfor mance at full rated current, Additionally , TS1085 provides excellent regulation over var iations due to changes in line, load and temperature. Outstanding features include low dropout per formance at rated current, fas t transient response, internal current limiting and ther mal shutdown protection of the output device. TS1085 are thr ee terminal regulators with fixed and adjustable voltage options av ailable in popular packages.

-60 70 dB VIN = Vout+3V Note 1: See ther mal regulation specification for changes in output voltage due to heating effec ts. Line and load regulation are measured at a constant junc tion temper ature by low duty cycle pulse tes ting. 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 deter mined by the input / output voltage difference and the output current. Guar anteed maximum pow er dissipation will not be available over the full input / output voltage range. Note 3: Quiescent current is defined as the minimum output current r equired to maintain the regulation. Note 4: The Output Capacitor does not have a theor etical upper limit and increasing its value will increase stability COUT=100uF or more is typical for high current regulator design.
