The TL783 is a variable three lead mains voltage regulator having an output range of 1.25 V to 125 V and a
DMOS output transistor which is able to handle in excess of 700 mA current.
It is specifically configured internally for working with high-voltage applications where ordinary bipolar voltage regulators become useless. High grade performance specifications, much enhanced than most bipolar regulators are implemented through a hi-breed circuit network and sophisticated layout technology.
In this innovative regulator device, the TL783 integrates the standard bipolar circuit technology with high-voltage double-diffused MOS transistors on one chip, to create a device attributed with properties for enduring higher voltages far higher than traditional 78XX bipolar integrated circuits. Due to the inability of secondary-breakdown and thermal-runaway situations inherently common with bipolar devices these become quite vulnerable to high voltages, unlike these the TL783 ensures full overload protection even under extreme operating conditions ranging up to 125 V across input to output.

The chip also includes an in-built current limiting feature, a safe operating area safeguard and also a thermal shutdown feature. In a worst case even if the ADJ gets isolated accidentally, all the above protection features stay functional.
The IC can be initiated and made functional just by adding a couple of external passive components. An input bypass capacitor becomes only essential in case the DC supply source is fetched from beyond 6 inches from the IC.
The ICalso exhibits excellent response to sudden output short circuits and sudden voltage spikes or transients.
