This is a voltage regulation in automotive electronic system video. This video explains the solution of voltage regulation problems in automotive electronic system. The problem of the regulation in automotive electronic system is the the supply from the battery s not constant. One of solution to this problem is linear LDO voltage regulator. It can be used for applications where the input voltage is always above the required output voltage and where high efficiency is not concern. Here is the tutorial video:

The solution of the problem is Not only linear LDO voltage regualtor, but also buck-boost switch mode regulator with internal switches. It is efficient solution with minimal external components for critical applications where the input voltage may drop below the required output voltage.
