Thermal Performance
The junction temperature is plotted versus the load current with a 5-V input
voltage and a 25
°
C ambient temperature in Figure 2
4. The low junction-to-
case thermal resistance of the PWP package, along with a good board layout,
helps to keep the junction temperature low at high output currents. With a 5-V
input source and a 3-A load, the junction temperture is approximately 47
°
C.
