DS3800DOWA1A is a Regulator Auxiliary Board manufactured and designed by General Electric as part of the Mark IV Series used in GE Speedtronic turbine control systems. It is a low-dropout regulator with auxiliary power control that delivers a steady 3.3-V supply at the output with 400 mA drive capability. It offers a regulated power output for systems that need a steady voltage supply with a low dropout voltage and has many input sources. With a low-dropout regulator for either the 5VCC or 5VAUX inputs and a low-resistance bypass switch for the 3.3VAUX, this single-output, multiple-input intelligent power source selection device can choose between both.


  • Automatic Source Selection of Input Voltage
  • Regulatory Output That Is Error-Free
  • Hysteresis-equipped 5-V Input Voltage Source Detector
  • Support for 400-mA load current with a 5-V or 3.3-V input source
