    Closed: How to Boost LM317 Output Curent

    LM317 is one of the most popular adjustable regulator chips. The output voltage of the regulator can be adjusted from 1.25V to 35V. However, the chip can deliver currents up to 1.5A which is not...

  4. Closed: Re: Low Noise Adjustable Linear AC-DC Power Supply

    That is my typo mistake in the schematic, they are rated at 35V in the bill of materials
  5. Closed: Re: Low Noise Adjustable Linear AC-DC Power Supply

    That's actually an RC filter. it won't reduce noises that much without a resistor.
  6. Closed: Re: Low Noise Adjustable Linear AC-DC Power Supply

    No, you gonna use a heatsink if the difference between the input and output voltage is high. Please check if LM317 or LM337 has introduced internal thermal protection. I didn't check
  7. Closed: Re: Low Noise Adjustable Linear AC-DC Power Supply

    1mV is high?! Really it is difficult to understand if it is the noise floor of the oscilloscope or not. Besides, in ALL power supplies when we increase the output current, then the noise will...

    Well, No. That is the feature of the function generator which does not go to 100%. actually 100% is not a PWM anymore, it is a flat DC line.
    Yes, the frequency can be increased but anyway it passed...
