APPLICATION SUGGESTION

NOTE

In order to avoid possible instability occuring into fi-

nal stage the usual suggestions for the linear power

stages are useful, as for instance :

- layout accuracy ;

- a 100nF capacitor corrected between supply pins

and ground ;

- boucherot cell (0.1 to 0.2

µF + 1 Ω series) between
