Electrical Characteristics Limits in standard typeface are for TJ = 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: VIN = VO(NOM) + 1V, IL = 1 mA, CL = 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.
