Note 1:
Dropout voltage is guaranteed by the p-channel switch resistance and assumes a maximum inductor resistance of 45m
.
Note 2:
The PWM-skip-mode transition has approximately 10mA of hysteresis.
Note 3:
The maximum output current is guaranteed by the following equation:
where:

f = operating frequency minimum
L = external inductor value
I

can be substituted for I
OUT(MAX)
(desired) when solving for D. This assumes that the inductor ripple current is
small relative to the absolute value.
Note 4:
POK only indicates the status of supplies that are enabled (except V7). When a supply is turned off, POK does not trigger
low. When a supply is turned on, POK immediately goes low until that supply reaches regulation. POK is forced low when all
supplies (except V7) are disabled.
Note 5:
Specifications to -40°C are guaranteed by design, not production tested.
