VOLTAGE REGULATORS

See Basic Electronics Course P57 for a complete discussion on VOLTAGE REGULATORS (subscription needed for access).
 Note: The Ground terminal is also called the Common terminal. 
By far the best site for looking up and purchasing Voltage Regulators is: DigiKey with over 9,000 items! 
There are many new surface-mount devices. You will need to download the exact specification sheet from the manufacturer for the pinout.
This list is only a sample of the most common types:
