Why thermal shutdown happens in a voltage regulator IC?

State the reason for thermal shutdown of IC regulator? Explanation: The IC regulator has a temperature sensor (built-in) which turn off the IC, when it becomes too hot (usually 125oC-150oC). The output current will drop and remains there until the IC has cooled significantly.

How do I turn off thermal shutdown?

Enabling or disabling thermal shutdown

  1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Advanced Options > Fan and Thermal Options > Thermal Shutdown and press Enter.
  2. Select a setting and press Enter.
  3. Press F10.

What is a thermal shutdown on a computer?

A thermal shutdown occurs when a computer case or central processing unit temperature reaches a critical level at which point the computer will automatically shut down to avoid permanent damage.

How do you make a constant current power source?

So to make a device that provides a constant current no matter the load, we have to use negative feedback and convert the current flowing through our load into a voltage. Luckily, there is a very easy way to convert a current to a voltage which involves using a small ohm resistor (in our case, a 0.1-ohm resistor).

How do you test a linear voltage regulator?

We take the probes of the multimeter and place the positive probe (normally the red probe) on the input pin of the voltage regulator and the negative probe (normally black probe) on the ground pin. The voltage that we should read should be higher than the voltage the regulator is rated to output.

How do you fix a computer that has a thermal shutdown?

If there is a lot of dust in the case or around the vents, clean it out. Dust acts as an insulator and can contribute to overheating. Remove the dust using short bursts from a can of compressed air. Hold the can vertically, perpendicular to the floor, when spraying.

Why does my computer keep doing a thermal shutdown?

This can be caused by a non-functioning system fan, or if the air ducts are blocked. Overheating can reduce the life of your computer, so you will want to resolve this as soon as you can.
