Notes
1. Minimum operating voltage, only if V
2. The total quiescent current is measured in the standby mode. Therefore, the enable inputs of regulators 1, 3, 4 and
3. The voltage of the regulator drops as a result of a V
4. The rise and fall times are measured with a 10 k pull-up resistor and a 50 pF load capacitor.
5. The delay time depends on the value of the reset delay capacitor:
6. The delay time depends on the value of the reset delay capacitor:
7. The drop-out voltage of regulators 1 and 2 is measured between pins V
8. At current limit, I
9. The foldback current protection limits the dissipated power at short-circuit (see Fig.6).
10. The drop-out voltage is measured between pins BU and REG2.
11. The drop-out voltage of the power switch is measured between pins V
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
