ST L7805CV 5V 1.5A voltage regulator is ST Microelectronic’s version of the 7805 voltage regulator is our favorite pick. The ST L7805CV is a very reliable option, can operate with input voltage up to 30V DC, and has a wide operating temperature. Together with one of the smallest available TO-220 heat sinks (19 x 13 x 6.5 mm) the max. power dissipation can be about 3W (natural convection) or 6W (forced air).
Mounting hardware is also included (M3 bolt, washer, nut).
We also have a set of 5 L7805CV, without heat sinks.
