3 Description
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.
