DESCRIPTION

These three terminal negative regulators are supplied in a hermetically sealed metal

package whose outline is similar to the industry standard TO-220 plastic package. All

protective features are designed into the circuit, including thermal shutdown, current

limiting and safe-area control. With heat sinking, they can deliver over 3.0 amps of

output current. These units feature 2% initial voltage tolerance, with 1.0% load

regulation and .015% line regulation.
