• Characteristics of the voltage transient on the output of a voltage regulator, as a consequence the transfer of energy related to an ion strike with the silicon, is a very critical issue in space applications. Large undershoots can cause erratic operation in memories and microprocessors, while overshoots of excessive amplitude can lead to the degradation - or even the destruction - of CMOS devices. As an example, for most FPGA the recommended operating voltage is 1.5V and the max. limit 1.6V (in some applications restricted to 1.575V to keep further safety margin). This latter applies to both static and dynamic operating conditions
