Notes
1. The quiescent current is measured in standby mode when R
2. The rise and fall times are measured with a 50 pF load capacitor.
3. The reset delay time depends on the value of the reset delay capacitor:
4. The dropout voltage of a regulator is the voltage difference between V
5. At current limit, V
6. The foldback current protection limits the dissipation power at short-circuit (see Fig.6).
7. The dropout voltage of regulator 2 is the voltage difference between V
