Control Circuitry/Power Transistor

Note 1: See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation

are measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the

output lead =1/18” from the package.

Note 2: Line and load regulation are guaranteed up to the maximum power dissipation of 5W. Power dissipation is

determined by the difference between input and output and the output current. Guaranteed maximum power

dissipation will not be available over the full input/output range.

Note 3: Quiescent current is defined as the minimum output current required in maintaining regulation. At 12V input/output

differential the device is guaranteed to regulate if the output current is greater than 10mA.
