THERMAL IMAGE
An example thermal image shows the temperature distribution on board. The test is done in still air at room tempera-
ture with 2.2W power dissipation in LT3080.
BYPASS CAPACITOR
Since the SET pin is a high impedance node, unwanted
signals may couple into the SET pin and cause erratic
behavior. This will be most noticeable when operating
with minimum output capacitors at full load current.
The easiest way to remedy this is to bypass the SET
pin with a small amount of capacitance from SET to
ground, 10pF to 20pF is sufficient. A 0.01uF bypass
capacitor is used on the demo board to provide a low-
noise output. Please refer to datasheet for details.
