APPLICATION INFORMATION
The basic application circuit is shown in Fig.24 and some typical applications are shown in Figs 25, 26 and 27.
In the basic application, the circuit provides two possibilities for supplies to peripheral circuits:
March 1994
regulated line voltage V
voltage is dependent only on the peripheral supply current. This application is the same as that used for
TEA1060/TEA1061, TEA1067 and TEA1068;
stabilized supply voltage for peripherals (V
