APPLICATION INFORMATION (continued)
Figure 31. Regulator for distributed supplies
MOUNTING INSTRUCTION
The power dissipated in the circuit must be removed
by adding an external heatsink.
Thanks to the Heptawatt package attaching the
hetsink is very simple, a screw or a compression
spring (clip) being sufficient. Between the heatsink
Figure 32. Mounting example
and the package it is better to insert a layer of silicon
grease, to optimize the thermal contact, no electri-
cal isolation is needed between the two surfaces.
