Practical considerations
Printed circuit board
The layout shown in
points of input 1 and input 2 must be well decoupled from the ground of the output through
which a rather high current flows.
Assembly recommendations
No electrical insulation is required between the package and the heatsink. Pin length should
be as short as possible. The soldering temperature must not exceed 260 °C for 12 seconds.
case temperature (R
An overload on the output (even if it is permanent), or an excessive ambient
temperature can be easily withstood.
The heatsink can have a smaller factor compared with that of a conventional circuit.
There is no damage to the device in the case of excessive junction temperature: only
