For such applications you should use a regulated power supply.
Icomo regulated power supply.
So in this instructable i m going to show you how to build your own regulated power supply why buy it if you can build it.
Regulated power supply is an electronic circuit that is designed to provide a constant dc voltage of predetermined value across load terminals irrespective of ac mains fluctuations or load variations.
Some power supplies even include fuses that will blow if the surge of electricity is too great as a way of protecting the equipment.
Thus a 5 v regulated power supply starts with a 12 vac transformer that delivers 12 v to the bridge rectifier which converts the ac to dc and drops the voltage down to about 9 v and then delivers the voltage to the filter circuit which smoothes out the ripples and passes the voltage on to the 7805 voltage regulator which holds the output.
A linear power supply or an adjustable power supply or a variable power supply can be a regulated power supply.
This part ensures the output delivered is smooth and unchanging regardless of draw or input.
What is a regulated power supply.
Rectifiers are classified into four types namely capacitor filter inductor filter lc filter rc filter.
The power supply is the first place to receive electricity with most designed to handle fluctuations in electrical current and still provide a regulated or consistent power output.
A regulated power supply is a very important component if you build electronics projects.

Problem 2 for the zener regulated power supply provided the rms value the transformer input voltage is 120v the operating frequency is 60hz n 4 r 1000 c 1mf the on voltage of diodes d and d2 is 0 7v and the zener voltage of diode d3 is 15v rz 0.
It may have any voltage value like 5v 10v 12v and many more.
But buying a good regulated power supply can be expensive.
A filter in the regulated power supply is mainly used for leveling the ac differences from the corrected voltage.
A voltage regulator in the regulated power supply is essential for keeping a steady dc output voltage by supplying load regulation as well as line regulation.
A regulated power supply can be any power supply as i said the quality it should possess is a constant output voltage.
