Part Number: LP3856-ADJ Tool/software: Hello,
We currently have a design in which we unintentionally have power being fed back into the Vout port of the device. The voltage being read at the terminal is -0.54V when the 6.4V rail is powered off. The…

Hi,
I have been using LP3856 for one of my circuit. But I found the output voltage is not stable. It keeps on increasing.
Here are my parameters:
Input voltage - 5.41 V
Output voltage…
Part Number: LP3856-ADJ Hello I use this component in a multi-power supply.
During the final test of the output voltage, I found that the deviations are greater than indicated in the data sheet.
Here are the results:
Here are the drawing of the…
Hi Bala,
The LP2954 has similar thermal performance to the LP3856-ADJ in the TO-263 and TO-220 packages. From the datasheet, θjc(bot) is 1.0 C/W and typical θch values will depend on the interface material:
The heat sink will need a θha such that…
