we r doing one project based on uc.we want 2 supply voltages one is
5v,and another is 3.3v.we r using adjustable voltage regulator to
adjust the o/p voltage.i will consume 50mA,but we slowly increase the
voltage, the current at the powersupply increse sharply that is more
than 1A it will consume.Plse tell me what r the reasons the power
supply in cc

What are the specifications for the active components?
If a part needs 5 volts, generally they mean 5 volts plus or
minus 10%. More than this and you will release the magic
smoke (and observe the increase in current as you do so).

Sp..
I realize that you may not fully comprehend the English language but,
you need to consider writing your future questions in English with
complete sentences.
In this case, describing what you're attempting to accomplish for the
sake of the design requirements. I wouldn't assume that everyone knows
what you mean when using acronyms. Example, "r," "cc," or
"plse."
Spell them out completely:
1. are
2. please
3. increase
Cheers,
Mr. Mentor

I'm sorry, my newsreader can't read SMS messages.

sounds like the power supply maybe going into oscillation or, you
have a component on the load that isn't able to handle the increase of
voltage.
