Video tutorial Voltage regulator tutorial & USB gadget charger circuit, This video covers the basics of linear voltage regulators – what they do, how to wire them up, and where to find them. Then I give a basic example of how to build a 5V supply that can be used to power USB powered gadgets.
The LM341 and LM78MXX series of three-terminal positive voltage regulators employ built-in current limiting, thermal shutdown, and safe-operating area protection which makes them virtually immune to damage from output overloads.

With adequate heatsinking, they can deliver in excess of 0.5A output current. Typical applications would include local (on-card) regulators which can eliminate the noise and degraded performance associated with single-point regulation.
