(1) To calculate the minimum input voltage for your maximum output current, use the following formula:
V
I
(min) = V
O
(max) + V
DO
(max load)
(2) Continuous output current and operating junction temperature are limited by internal protection circuitry, but it is not recommended that
the device operate under conditions beyond those specified in this table for extended periods of time.
(3) The minimum IN operating voltage is 2.7 V or V
O(typ)
+ 1 V, whichever is greater. The maximum IN voltage is 5.5 V. The maximum
output current is 200 mA.
(4) If V
O
≤ 2.5 V, then V
Imin
= 2.7 V, V
Imax
= 5.5 V:
If V
O
≥ 2.5 V, then V
Imin
= V
O
+ 1 V, V
Imax
= 5.5 V.
