  • DC/DC Converters With Linear Regulators

    is required, the ripple of a switching regulator can be reduced by a linear regulator. The output ripple of a standard DC/DC converter is between 0.5% and 1% of its nominal output voltage. For applications that require a lower output ripple, linear regulators can be used to reduce a converter's output

  • Linear versus switching regulators in industrial applications with a 24-V bus

    This article compares three different solutions that provide a 5-V output at 100 mA from. a 24-V bus. A synchronous step-down (buck) converter is. compared to an integrated linear regulator and a discrete. linear regulator. Size, efficiency, thermal performance,. transient response, noise

  • Switching Regulators

    higher efficiency than linear regulators. The one disadvantage of the switching regulator is noise. Any time charge is moved in discrete packets, noise or ripples are created. But noise can often be minimized using specific control techniques and through careful component selection.

  • Protection For Switching Regulators

    Step down regulators are used to convert a higher DC voltage to a lower required DC voltage. Switching regulators offer higher efficiency than the linear regulators, excellent load step response and higher output currents. They are also more expensive than linear regulators and produce more noise

  • The lowdown on lowdropout regulators

    and rectified to 12 or 24 Vdc. These values get stepped down to a lower dc voltage. A step-down switching regulator typically performs the dc/dc conversion for maximum power conversion efficiency. Switching regulators display conversion efficiencies over 90% compared to the maximum 50% of linear regulators

  • Linear Voltage Regulators

    Linear voltage regulators use an active pass element (bipolar or MOSFET) to drop the input voltage down to the regulated output voltage. They operate by using a voltage-controlled source to force a fixed voltage to appear at its output terminal. Control circuitry monitors this output voltage

  
Discussions about Linear Regulator Schematic
  • Re: AC to DC converter

    The disadvantages of this schematic are that you have to transform the voltage. If you dimension it for 6V input it will nor work for 2.4V, if you dimension it for 2.4V you`ll waste nearly 70-80% of your energy with this linear concept. I would rectify and buffer the voltage in the ra...

  • Re: DC Power Supply

    I checked the National Semiconductor G.P. linears and I saw that your schematic corresponds to a LM117 suffix T or K (TO-220 and TO-3 respectively), but a schematic for a similar regulator using a LM317 is somewhat more complex, if you have the National "General Purpose Linear Devices" goto page 1-4...

  • Re: I Really Want to Become an Expert in Electronics, But I Don't Know How.

    Linear Tech http://www.linear.com/ has a SPICE simulator available for free that is very powerful. Their reason for giving it away is to allow engineers to become familiar with their switching regulators and other somewhat complex chips. But, it works very well for simple circuits such as a resistor...

  • Re: Circuit Diagram for a 12V LED Lamp

    Another possibility is using a switching regulator modified as a current source as they are used for LED backlight applications. You find them at linear.com or at ti.com together with schematics and application notes. The advantages are: 1. No energy is wasted by resistors...

  • Re: Faulty Power Supply

    It's sounds like you've popped the voltage regulator. Imagine that there is a voltage regulator chip, or circuit, in there that gets 40V as an input and outputs a variable voltage. If the voltage regulator dies, then the raw 40V input will be on the output. I would take it apart and see what sort...

  • Re: 0 to 1 amps variable milli amps source

    Yes, the LM317 three-terminal regulator was designed to be a voltage source, rather than a current source, but nonetheless it's long been a rather popular CS chip, thanks to its low 1.2-volt reference voltage. For example, to get a 1A current source, just add a 1.2-ohm current-sensing resistor to...
