700-mA, 125-V, adjustable linear voltage regulator - TL783


The TL783 device is an adjustable three-terminal high-voltage regulator with an output range of 1.25 V to 125 V and a DMOS output transistor capable of sourcing more than 700 mA. It is designed for use in high-voltage applications where standard bipolar regulators cannot be used. Excellent performance specifications, superior to those of most bipolar regulators, are achieved through circuit design and advanced layout techniques.


  • Output Adjustable From 1.25 V to 125 V when Used with an External Resistor Divider
  • 700-mA Output Current
  • Full Short-Circuit, Safe-Operating-Area, and Thermal-Shutdown Protection
  • 0.001%/V Typical Input Voltage Regulation
  • 0.15% Typical Output Voltage Regulation
  • 76-dB Typical Ripple Rejection
