Preliminary specification
Multiple voltage regulator with switch
TDA3608Q
Notes
1.
2.
Minimum operating voltage, only if V
P
has exceeded 6.5 V.
The quiescent current is measured in the standby mode. So, the enable inputs of regulators 1, 3 and the switch are
grounded and R
L(REG2)
=
∞
(see Fig.6).
The voltage of the regulator sinks as a result of a V
P
drop.
The rise and fall time is measured with a 10 k
pull-up resistor and a 50 pF load capacitor.

4.
5.
The delay time depends on the value of the capacitor:

10. The drop-out voltage measured between BU and REG2.
11. The drop-out voltage of the power switch is measured between V
P
and SW.
12. The maximum output current of the power switch is limited to 1.8 A when the supply voltage exceeds 18 V.
13. At short-circuit, I
sc
of the power switch is held constant to a lower value than the continuous current after a delay of
at least 10 ms (see Fig.5).
14. The reverse current of the back-up switch is measured when flowing out of pin V
P
with V
P
= 0 V.
The drop-out voltage of regulators 1, 2 and 3 is measured between V
P
and REGn.
At current limit, I
REGmn
is held constant (see Fig.4 for behaviour of I
REGmn
).
The foldback current protection limits the dissipated power at short-circuit (see Fig.4).
The peak current of 300 mA can only be applied for short periods (t < 100 ms).
