DESCRIPTION
New circuit design and processing techniques are used to provide the high output current without sacrificing the regulation characteristics of lower current devices. Parameters with tightened specifications include output voltage tolerance, line regulation, and load regulation. The 3 amp regulator is virtually blowout proof. Current limiting, power limiting, and thermal shutdown provide the same high level of reliability obtained with these techniques in the LM109 1 amp regulator. No external components are required for operation of the LM123. If the device is more than 4 inches from the filter capacitor, however, a 1 μF solid tantalum capacitor should be used on the input. A 0.1 μF or larger capacitor may be used on the output to reduce load transient spikes created by fast switching digital logic, or to swamp out stray load capacitance.
