Electrical Characteristics
(Note 4)
(Continued)
Note 1:
Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device
is intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2:
The CB pin must not be higher than 8V above the V
SW
.
Note 3:
The human body model is a 100 pF capacitor discharged through a 1.5k
resistor into each pin. The machine model is 200 pF capacitor discharged directly
into each pin.
Note 4:
All limits are guaranteed at room temperature (standard type face) and at
temperature extremes (bold type face)
. All room temperature limits are 100%
tested. All limits at
temperature extremes
are guaranteed via correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate
Average Outgoing Quality Level (AOQL).
Note 5:
For this test, the COMP/SD pin must be left floating.
Note 6:
For this test, the COMP/SD pin must be pulled low.
Note 7:
The over-voltage protection is specified with respect to the feedback voltage. This is because the over-voltage protection tracks the feedback voltage. The
overvoltage protection threshold is given by adding the feedback voltage, V
FB
to the over-voltage protection specification.
Note 8:
The COMP/SD pin should be pulled to ground to turn the regulator off. The voltage on the COMP/SD pin must be below the limit for Output = Low to keep
the regulator off.
