Notes
1. The quiescent current is measured in standby mode when R_L = ∞.
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:
t_d(rst)= ^C-----R----^E_I--c-^S--_h-^C----^A---^P-- × V_th(rst) = C_RESCAP × (750 × 10³)[s]
4. The dropout voltage of a regulator is the voltage difference between V_P and V_O(REGn).
5. At current limit, V_O(REGn) is held constant (see Fig.6).
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_BUCAP and V_O(REG2).
