The following schematic showsIncreasing Output Voltage of a Fixed Linear Regulator Circuit Diagramusing 3-terminal shunt regulators or references. The 3-terminal shunt regulators provide their precision function to turn the medium accuracy linear regulators into precision ones.

Fixed Linear Regulator Circuit Diagram

As shown in the circuit above, both the output voltage and its accuracy are performed by the TLV431, R1 and R2. The 5A output current, output current limiting, and thermal shutdown of the regulator’s features are still available whilst combining the best of both devices.

The circuit is very simple. See the output voltage computation examples in the other part ofIncreasing Output Voltage of a Fixed Linear Regulator Circuit Diagramin this pdf filetype (source: diodes.com)
