1A Fixed Voltage – 78/79 series TO-220 Single Gauge

The 7800 and 7900 series of three-terminal positive and negative voltage regulators can deliver over 1A of regulated output curent in a choice of several output voltages (subject to adequate heat sinking). Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

  • TO-220 single gauge package
  • Internal current limiting, thermal shut-down and safe area protection
For suitable heat sinks and themal pads see Semiconductor hardware section.
