Notes: RӨJA is the sum of the junction-to-case and case-to-ambient thermal resistances. The case thermal reference is defined

at the solder mounting surface of the drain pins. RӨJA is guaranteed by design while RӨCA is determined by the user’s board

design. RӨJA shown below for single device operation on FR-4 PCB in still air.

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.

COUT=100uF or more is typical for high current regulator design.
