The TL783C 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 TL783C 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 TL783C 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 inadvertently disconnected, 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.
