Electrical Characteristics (continued)
Limits in standard typeface are for T_J = 25°C, and limits in boldface type apply over the full operating temperature range.
Unless otherwise specified: C_IN = 4.7 μF, V_IN = V_O(NOM) + 1V, I_L = 1 mA, C_OUT = 10 μF for 5V parts or C_OUT = 22 μF for 3.3V
parts, Feedback pin is tied to V_TAP pin, Output pin is tied to Sense pin, V_S/D = 2V.

(10) Dropout detection comparator threshold voltages are expressed in terms of a voltage differential measured at the Feedback terminal
below the nominal reference voltage, which is the reference voltage measured with V_IN = V_O(NOM) + 1V. To express these thresholds in
terms of output voltage change, multiply by the error amplifier gain which is V_O/V_REF = (R1 + R2)/R2 (see Basic Application Circuit).
(11) Vshutdown ≤ 1.1V, V_IN < 30V, V_OUT = 0V.
