I would like to use the uPC7805AHF with the input voltage set to 30 V, but the recommended operating conditions list the input voltage as 25 V max. What problems would occur if the uPC7805AHF is used with the input voltage set to 30 V?
The uPC7805AHF can be used safely at 30 V without degradation of characteristics or damage. However, caution is required for the absolute maximum rating for the internal power dissipation (PT). Be sure to use the uPC7805AHF in a range that does not exceed absolute maximum rating PT.
