  • TPSM84205  -  1.5A, 28V Input, 5V Output TO-220 Power Module


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.


  • ±1% Output Tolerance at 25°C
  • ±2% Output Tolerance Over Full Operating Range
  • Thermal Shutdown
  • Internal Short-Circuit Current Limiting
  • Pinout Identical to µA7800 Series
  • Improved Version of µA7800 Series
