... The LM1084 regulates the voltage that appears between its output and ground pins, or between its output and adjust pins. In some cases, line resistances can introduce errors to the voltage across the load. To obtain the best load regulation, a few precautions are needed. Figure 12 shows a typical ap ...

Immunity-aware programming

When writing firmware for an embedded system, immunity-aware programming refers to programming techniques which improve the tolerance of transient errors in the program counter or other modules of a program that would otherwise lead to failure. Transient errors are typically caused by single event upsets, insufficient power, or by strong electromagnetic signals transmitted by some other ""source"" device.Immunity-aware programming is an example of defensive programming and EMC-aware programming. Although most of these techniques apply to the software in the ""victim"" device to make it more reliable, a few of these techniques apply to software in the ""source"" device to make it emit less unwanted noise.
