DESCRIPTION/ORDERING INFORMATION  
The TL783 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.  
As a state-of-the-art regulator, the TL783 combines standard bipolar circuitry with high-voltage double-diffused  
MOS transistors on one chip, to yield a device capable of withstanding voltages far higher than standard bipolar  
integrated circuits. Because of its lack of secondary-breakdown and thermal-runaway characteristics usually  
associated with bipolar outputs, the TL783 maintains full overload protection while operating at up to 125 V from  
input to output. Other features of the device include current limiting, safe-operating-area (SOA) protection, and  
thermal shutdown. Even if ADJ is disconnected inadvertently, the protection circuitry remains functional.  
Only two external resistors are required to program the output voltage. An input bypass capacitor is necessary  
only when the regulator is situated far from the input filter. An output capacitor, although not required, improves  
transient response and protection from instantaneous output short circuits. Excellent ripple rejection can be  
achieved without a bypass capacitor at the adjustment terminal.
