ALL VOLTAGE OPTIONS ELECTRICAL CHARACTERISTICS (continued)
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 4.7 μF for 3.3V parts. Feedback pin is tied
to V Tap pin, Output pin is tied to Output Sense pin.
