L7805CV STMicroelectronics 5V Linear Voltage Regulator (TO-220-3)

Where the ABV part targets designs that need precision-grade output tolerance, this CV version is the standard-grade 7805 that covers the vast majority of everyday regulation needs - most projects running 5V logic from a higher-voltage supply don't need the tighter tolerance and are better served by the standard part's lower cost. Same core specification otherwise: 10V to 35V input, a steady 5V out at up to 1.5A, TO-220 package for heatsink mounting when the thermal load calls for it. Keeping both grades in stock means a builder can pick precision when it matters and the standard part when it doesn't, rather than over-paying for tolerance a project never uses.
