1.5A Low Dropout Positive Voltage Regulator
TO-263
Low Dropout Voltage 1.3V max.
Pin assignment:
1. Ground / Adj
2. Output
3. Input
Pin 2 connect to heatsink
General Description
The TS1086 Series are high performance positive voltage regulators are designed for use in applications requiring low
dropout performance at full rated current, Additionally, the PJ1086 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 TS1086 Series are
three terminal regulators with fixed and adjustable voltage options available in popular packages.
This series is offered in 3-pin TO-263, TO-220, TO-252 and SOT-223 package.

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.
