7805 Variable Voltage Regulator Circuit. A 7805 regulator and 10v zener give an output adjustable from 5 to 15 volts. For example if the input voltage is 12v and you are consuming 1a then 12 5 1 7w.
Variable Voltage Power Supply Circuit Using The Lm317t Voltage Regulator To Produce A 1 5a Power Supply Circuit Electronic Circuit Projects Electronics Circuit from www.pinterest.com
Currently the 7805 voltage regulator ic is manufactured by texas instruments on semiconductor stmicroelectronics diodes incorporated infineon technologies etc. This is variable regulated power supply using 7805 and op amp there is an adjustable output range of 5v to 13v max output current of 1a. The output current of this ic can go up to 1 5a.
For example if the input voltage is 12v and you are consuming 1a then 12 5 1 7w.
This is attained by adding two resistors r1 and r2 as shown in figure. 7805 variable voltage regulator.
