The LM7812 series of three terminal positive regulators are handy since they are offered in the TO-220 package and have a number of set output voltages.The L78 series of three-terminal positive regulators is available in TO-220, These regulators can provide local on-card regulation, eliminating the distribution problems associated with single-point regulation. Each type embeds internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.
