Power Dissipation vs Output Current
Note 1:
All data listed in the above graphs, except for derating data, has been developed from actual products tested at 25°C. This data is considered typical data for the ISR.
Note 2:
Minimum Vin data is typical and is not guaranteed. The data corresponds to a 2% output voltage drop.
Note 3:
Thermal derating graphs are developed in free air convection cooling of 40-60 LFM with no optional heat tab soldered in a printed circuit board. (See Thermal Application Notes).
