What is a Voltage Regulator? EAGLE Blog
Watch video · Whenever we need a constant and specific value of voltage without fluctuation we use voltage regulator IC. They provide a fixed regulated power supply. We have 78XX (7805, 7806, 7812 etc) series voltage regulators for positive power supply and 79XX for negative power supply. But what if need to vary the power supply voltage, so here we have... The voltage regulator IC maintains the output voltage at a constant value. The xx in 78xx indicates the fixed output voltage it is designed to provide. 7805 provides +5V regulated power supply. Capacitors of suitable values can be connected at input and output pins depending upon the respective voltage levels.

7805 voltage regulator question All About Circuits
This circuit diagram shows you how to make a 5V to 12V variable DC power supply from a fixed 5V regulator IC 7805. This is attained by adding two resistors R1 and R2 as shown in figure. When the resistors R1 and R2 are added the equation for the output voltage of 7805 becomes how to ask someone for land The output voltage is variable from the regulator output to the regulator output plus the zener voltage. E.G. A 7805 regulator and 10V zener give an output adjustable from 5 to 15 Volts. The regulator may be changed to provide different output voltages as may the zener. the zener should be rated a ….
