DESCRIPTION
These three terminal negative regulators are supplied in a hermetic surface mount
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.

Notes:
1. Line and Load Regulation are measured at a constant junction temperature using a low duty cycle pulse technique.
Although power dissipation is internally limited, regulation is guaranteed up to the maximum power dissipation of 30 W.
Power dissipation is determined by the input/output differential voltage and the output current. Guaranteed maximum
power dissipation will not be available over the full input/output voltage range.
2. Guaranteed by design, characterization or correlation to other tested parameters.
3. The • denotes the specifications which apply over the full operating temperature range.
