Although power dissipation is internally limited, these specifications are applicable for power dissipation up to
625mW. I

Regulation is measure at constant junction temperature, using pulse testing with a low duty cycle. Changes in
output voltage due to heating effects are covered under the specification for thermal regulation.
Thermal resistance of the TO-92 package is 180
