description
Eachfixed-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 make
the devices essentially immune to overload.
The TL780-xxC series regulators are characterized for operation over the virtual junction temperature range
of 0°C to 125°C.
