Engineeer Comments

While switching regulators might be all the rage, many - if not most - voltage regulation problems can also be solved in an easier way.

A design based on the UA7805 is unlikely to win you media acclaims or an award for innovation - millions of this Evergreen component have been sold in literally thousands of designs since the time when yours truly was but a lowly cadet. A testament to the popularity is that the UA7805 is not only available from Texas Instruments, but also various second sources (leading to the famous debate of UA7805 vs LM7805).

The UA7805 is but a small part of the family, which has since been extended to cover various other voltages not related to TTL's famously infamous 5V potential. Nevertheless, the operational principle always is the same - connect the ground pin to your application's ground, and the voltage regulator burns away the excessive voltage.

Another interesting aspect is that the parts can be cascaded. A classic application combines a switching regulator with various linear regulators to generate various independent voltage levels.
