Output Capacitors.
The low cut off frequency due to output capacitor depending on the load is given by:
With C
Stability
A good layout is recommended in order to avoid oscillations. In general, the designer must pay attention on the
following points:
-Short wires of components and short connections.
-No ground loops.
-Bypass of supply voltage with capacitors as nearest as possible to the supply I.C. pin. The low value (polyester)
capacitors must have good temperature and frequency characteristics.
-No sockets.
The heatsink can have a smaller factor of safety compared with that of a conventional circuit. There is no device
damage in the case of excessive junction temperature: all that happens is that P
reduced.
