description
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 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.
The TL783C is characterized for operation over the virtual junction temperature range of 0

C to 125
