LM317 smooths but doesn’t regulate

Michael Dunn discuss about a circuit that smooths ripple and noise but doesn't regulates the output. A well known power supply circuit is the capacitance multiplier. It doesn't regulate, but instead reduces ripple & noise while the output tracks at some fraction of the input...

Circuit adds foldback-current protection

by Rafael Garcia-Gil @ edn.com: For many applications that require power-supply currents of a few amperes or less, three-terminal adjustable-output linear voltage regulators, such as National Semiconductor's LM317, offer ease of use, low cost, and full on-chip overload protection. The...

Use an LM317 as 0 to 3V adjustable regulator

by Vladimir Rentyuk @ edn.com: Most engineers know that they can use an inexpensive, three-terminal adjustable regulator, such as Fairchild Semiconductor’s LM317, as an adjustable regulator to only some necessary value of voltage, such as 36 or 3V. This value cannot be less than...
