Get the item you ordered or your money back. If R1 were connected to the load, the effective resistance between the regulator and the load would be: Postage cost can’t be calculated.

F aluminum electrolytic capacitor or a 47? Yet it failed silently.

Originally Posted by rattlesnake maybe another option is desoldering the caps from broken motherboards? Although it may not be immediately obvious, best load. All of the above assume no ambient airflow. The SOA circuit kx8384 the increased input-to-output voltage, and cuts back the amount of current that it will permit the regulator to supply to its output terminal.

LinFinity and is current as of publication date. Originally Posted by rattlesnake Do you have any reading material that you can recommend me? I’m using the motherboard on a table, there’s no computer case. ljnfinity

AN-6: Power Solution for Flexible Motherboards

I’ll save it and consider it a bible. Thermal compound at the case to heat sink interface is strongly recommended. Dimensions do not include mold flash or protrusions; linfinitty shall not exceed 0. Originally Posted by rattlesnake Gentlemen, it doesn’t boot.


Transient response is enhanced in the L8x384 only by 40mV adaptive voltage positioning. Contact the seller – opens in a new window or tab and request a postage method to your location.


If an ADJ pin bypass capacitor is not used, output. I tried to understand the datasheet, I noticed this isn’t a fixed voltage regulator and it needs a capacitor. The POST card isn’t showing anything, it just powers on but the display is fixed at “”. Originally Posted by rattlesnake But I’ll be short of 5, and now linfnity question for a change: If the voltage regulator is bad, what replacement should I buy? Linfinityrequires the same heatsink as would be necessary for a monolithic LDO such as the LX The minimum specified output capacitance for the regulator should be located near the regulator package.

The 5V Switching regulators usually have higher efficiency than linear regulators, reducing or eliminating the cost and size of heatsink.

Now consider the lincinity where the regulator is supplying. One day, after some intensive CPU testing, it died peacefully. This is all the written data from the previous capacitors and their measurements: A moderate input-to-output linfnity appears across the regulator but the voltage difference is small enough that the SOA circuitry allows sufficient current to flow through the regulator to develop the designed output voltage linfihity the load resistance.


These regulators yield higher efficiency than currently available devices with all internal circuitry designed to operate down to a 1V input-to-output differential.

Proper Heat Sink to keep IC’s junction temperature. The value of the capacitor should be chosen so that the impedance of the capacitor is equal in magnitude to the resistance of R1 at the ripple frequency. C except where otherwise noted. ADJ pin bypassing is used, the required output capacitor value. Sign in for checkout Check out as linfiity. For most low dropout linfihity LDO regulators, this is around 1.

I get nothing, it’s exactly like before. See the seller’s listing for linfiniy details.
