TL783 Adjustable Regulator : Pinout, Price and Datasheet

The IC TL783 is a 3 terminal high voltage adjustable regulator that can be used for getting a continuously variable output between 1.25 V to 125 V DC.

The device has an in-built DMOS MOSFET which enables the user to obtain a decent current at around 700 mA for the entire voltage range. 

It is designed for use in high-voltage applications where standard bipolar regulators cannot be used. In these applications, other typical voltage regulator such as LM338 etc seem greatly ineffective.

The IC TL783 is extremely good with its high voltage regulation feature due to its state-of-the-art technology that includes standard bipolar circuitry along with a special high-voltage double diffused MOSFET output stage. With these advanced layouts the device is able to ideally adapt to voltages at much higher levels which other BJT based designs simply fail.

Due to the elimination of secondary-breakdown and thermal-runaway characteristics, which are normally a part of typical BJT based outputs, the TL783 is able to execute an optimal overload protection even while working with potentials up to 125 V input-output differential.

The device is further packed with many outstanding features such as over-current limiting, safe-operating-area (SOA) protection, and thermal shutdown.

The above mentioned protection features remain active even in a situation where the ADJ pin of the IC is accidentally left open.
