Electrical Characteristics Limits in standard typeface are for T_J = 25˚C, bold typeface applies over the full
operating temperature range. Limits are guaranteed by production testing or correlation techniques using standard Statistical
Quality Control (SQC) methods. Unless otherwise specified: V_IN = V_O(NOM) + 1V, I_L = 1 mA, C_L = 2.2 µF for 5V parts and
4.7µF for 3.3V parts. Feedback pin is tied to V Tap pin, Output pin is tied to Output Sense pin.
