(13) Turn-on delay is the time interval between the low to high transition on the shutdown pin to the output voltage settling to within 5% of the

nominal value. Turn-off delay is the time interval between the high to low transition on the shutdown pin to the output voltage dropping

below 50% of the nominal value. The external load impedance influences the output voltage decay in shutdown mode.

(14) Error Flag threshold and hysteresis are specified as the percentage below the regulated output voltage.
