Stability
A good layout is recommended in order to avoid
oscillations.
Generally the designer must pay attention on the
followingpoints:
- Shortwires of componentsand short connec-
tions.
- No ground loops.
- Bypass of supply voltagewith capacitorsas
nearestas possible to the supply I.C.pin.The
low value(poliester)capacitorsmust
good temperatureand frequencycharac-
teristics.
have
- No sockets.
2)the heatsinkcan have a smaller factorof safety
compared with that of a conventional circuit.
There is no device damage in the case of ex-
cessive junction temperature: all that happens
is that P
O
(and therefore P
tot
) and Id are re-
duced.
APPLICATION SUGGESTION
The recommended values of the components are
