Notes to the characteristics
1. Minimum operating voltage, only if VP has exceeded 6.5 V.
2. Enable and ignition inputs are low and regulator 2 is unloaded.
3. Voltage drop due to load condition.
4. The spread on tracking is one sigma value.
5. Ignition output voltage will be less than or equal to the output voltage of regulator 2.
6. IREG1 = 5 mA.
7. The drop-out voltage of regulator 1 is measured between VP and REG1.
8. At current limit, IREGm is held constant (see Fig.5).
9. The foldback current protection limits the dissipated power at short-circuit (see Figs 5 and 6).
10. The cross talk of regulator 1 is measured with an IREG2 = 0.5 mA up to 30 mA with an input frequency of fi = 100 kHz.
11. IREG2 = 5 mA.
12. The drop-out voltage of regulator 2 is measured between VP and REG2.
13. The cross talk of regulator 2 is measured with an IREG1 = 0.5 mA up to 100 mA with an input frequency of
fi = 100 kHz.
14. The drop-out voltage of the power switch is measured between VP and Vsw.
