DESCRIPTION/ORDERING INFORMATION

TL780 SERIES

POSITIVE-VOLTAGE REGULATORS

SLVS055M – APRIL 1981 – REVISED OCTOBER 2006

• ± 1% Output Tolerance at 25 ° C • Internal Short-Circuit Current Limiting

• ± 2% Output Tolerance Over Full Operating • Pinout Identical to µ A7800 Series

Range

• Improved Version of µ A7800 Series

• Thermal Shutdown

Each fixed-voltage precision regulator in the TL780 series is capable of supplying 1.5 A of load current. A unique

temperature-compensation technique, coupled with an internally trimmed band-gap reference, has resulted in

improved accuracy when compared to other three-terminal regulators. Advanced layout techniques provide

excellent line, load, and thermal regulation. The internal current-limiting and thermal-shutdown features

essentially make the devices immune to overload.
