Table 5.
1. See
2. Measured output current when the output voltage has dropped 100mV from its nominal value obtained at
3. Vs-Vo measured when the output voltage has dropped 100mV from its nominal value obtained at
4. Guaranteed by design.
Table 6.
1. When Vo becomes lower than 4V, the reset reaction time decreases down to 2µs assuring a faster reset
