Multiple voltage regulators with switch
TDA3608Q; TDA3608TH
10. The peak current of 300 mA can only be applied for short periods (t < 100 ms).
11. The dropout voltage is measured between pins BU and REG2.
12. The dropout voltage of the power switch is measured between pins VP and SW.
13. The maximum output current of the power switch is limited to 1.8 A when VP >18V.
14. During short-circuit, current Isc of the power switch is held constant to a lower value than the continuous current after
a delay of at least 10 ms. Furthermore, a foldback function is activated after the delay. When VSW < 3.5 V, the
short-circuit current is reduced to 0.5 A (typical value). The short-circuit protection of the power switch functions best
when C1 = 220
F and C2 = 10 F.
15. The reverse current of the backup switch is the current which is flowing out of pin VP at VP =0V.
