Note:
1. See thermal regulation specification 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.
2. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is
determined by the input / output voltage difference and the output current. Guaranteed maximum power
dissipation will not be available over the full input / output voltage range.
3. Quiescent current is defined as the minimum output current required to maintain the regulation.
4. The Output Capacitor does not have a theoretical upper limit and increasing its value will increase stability.
C
OUT
=100uF or more is typical for high current regulator design.
