Notes
1. Minimum operating voltage, only if V
2. The quiescent current is measured in the standby mode with pins EN1, EN2 and ENSW connected to ground 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 capacitor connected to pin C
6. The delay time depends on the value of the capacitor connected to pin C
7. The drop-out voltage of regulators 1, 2 and 3 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 switch is limited to 1.8 A when the supply voltage exceeds 18 V. A test mode is
13. At short-circuit, I
