LM 7805 is a fixed linear voltage regulator IC, it gives a constant output of 5v for any input ranging between 7 V to 24 V. In all voltage regulators IC, 7085 stands on top because most of the electronics circuits require 5v as a basic voltage supply, and getting any battery with exact 5v output is not that easy.

Also, we suggest using a capacitor to minimize voltage fluctuation with a heat sink to avoid damage because of the heat, The heat generated by the LM7085 IC can be calculated by the following formula:

  • Heat generated by IC = ( input voltage – 5 ) X ( output current )
