Multiple output voltage regulator

TDA3602

Notes

1. Minimum operating voltage only if VP has exceeded 8 V.

2. In the sleep mode, Regulators 1 and 2 are off. In the coma mode, the state control circuit is also switched off, to make

the quiescent current as low as possible.

3. Hold circuit can sink this current in the RESET state and the ON state.

4. The foldback current protection limits the dissipated power at short-circuit (see Fig.5).

5. The drop-out voltage of Regulator 3 is measured between Vbu and VREG3 (pins 8 and 7).

6. At current limit, IREGm is held constant (behaviour in accordance with the broken line in Fig.5).
