LM317 can be used for regulated dc power supply upto 37V. For more voltage range, a zener can be connected at the reference pin.

Why an IC is not working?
This question would be easier to answer if the type of IC was specified.But generally, there are 3 reasons an IC will not work:1. It is broken. If a large voltage or shock has been applied to it, or the power hooked up to it in reverse, an IC will usually burn out. This may or may not be accompanied with the release of the Magic Blue Smoke. (http://en.wikipedia.org/wiki/Magic_smoke)2. Your power supply is dead or not outputting enough voltage. If the voltage supplied is too low for the IC to use, it may not function properly or at all. Check the power supply.3. The circuit the IC is in is broken. Check all the wires/solder points. Test the IC in a known working circuit.
What is the use of IC 555 in generating pulse width modulation signal?
A pulse width modulated signal would be very useful in a switching power supply. This is but one example. Note, however, that there are better examples than the 555 for use in a switching power supply.
How do you power a 5 V device at a 12 V power supply?
You must step it down to 5 volts. 12 volts will most likely cause damage. Radioshack, or any small parts store should have a small package DC power supply converter IC. I got one several years ago for ~1 -2 dollars. If you have a power supply that converts to 12 volts, you can use this chip in conjunction with a potentiometer to tune the output to ~1.5 - supply voltage (in your case 12 volts). This is a simple and flexible option that does not require a whole lot of know how (or cost), as long as the power required (IE current) is not beyond the rating of the IC.
Why the 14th pin and 7th pin is connected to Vcc and Ground respectively in IC 7408?
7408 is an active componet that need power supply to work otherwise it wont work
What is the most used ic among ttl and cmos?
ic 8284
What is the use of ic 7806?
IC 7806 is the voltage regulator that gives 6V dc voltage from 230V ac power supply. It is used to give power supply to the IC which operates on 6V.
Why do you supply DC power?
DC power supply is used to power the IC's and other active and passive devices.It is provide to amplify the weak signal with the help of amplifiers.
What is the use of IC 7414?
this IC is used as a regulated power supply A: DEFINITELY not it is an hex Schmidt trigger inverter function is Y=A inverter
Where you use HCF4046?
The HCF4046 integrated circuit is a phased locked loop control IC, typically this would be used in a switched mode power supply, however these are only ever needed where the load is frequency dependent and also drifts. In PC PSUs, a PWM IC is used instead to regulate power very precisely, such as a TL494. In short, the 4046 would not be used in any computer equipment!

Ac and dc load line of BJT-explain?
when the dc supply given, dc load line lies in the Ic and Vcc. when the AC supply given, AC load line lies in the Ic and Vcc.
Why the 14th pin and 7th pin is connected to Vcc and Ground respectively in IC 7408?
7408 is an active componet that need power supply to work otherwise it wont work
