Only if your LM317 is typical or is worse. Do you like to gamble?kalaman said:For 1A , 25C temperature , 16.2V unregulated voltage and 14.5V output my source is useless. Is it true ?
On the National datasheet, all the relevant specs state that the conditions areHero999 said:Also, is 16.2V the peak voltage on the capacitor?
When you draw a load there will be ripple which will make the situation even worse.
Audioguru,
What you're saying (about 3V) sounds reasonable but where on the datasheet does it say that? I agree that it mentions the typical values but it doesn't mention the worst case values.
3V ≤ (VIN − VOUT) ≤ 40V
I noticed that but it doesn't say that it needs to be >3 in order to work.Roff said:On the National datasheet, all the relevant specs state that the conditions are
