Working Principle

At its heart, the LD39200DPUR is a voltage regulator. It comprises of an internal linear differential amplifier, a current limiting layer, a bandgap reference, a feedback circuit, and a P-MOSFET transistior. The internal linear differential amplifier is used to compare the selected output voltage to the feedback voltage. The amplifier then produces an error signal which is used to control the output voltage via the P-MOSFET transistor and the current limiting layer. The internal bandgap reference provides high accuracy and provides stable voltage regulation even at low input voltages. The feedback circuit is used to provide the error signal to the internal linear differential amplifier, helping to keep the output voltage stable against line and load changes.

The LD39200DPUR is a low dropout, adjustable, linear voltage regulator from AUK Corporation with a wide range of application possibilities. It offers the user a wide range of output voltage options, allowing it to be used for many different load-level applications. Its high precision voltage regulation combined with its high output current capacity make it ideal for use in many applications.
