DESCRIPTION
These three terminal positive regulators are supplied in a hermetically sealed metal
package whose outline is similar to the industry standard TO-247 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 0.3% load
regulation and .01% line regulation.
