Note 2: Limits are 100% production tested at T
A
= +25°C. Limits over the operating temperature range are guaranteed by design.
Note 3: Dropout voltage is defined as V
IN
- V
OUT
when V
OUT
is 2% below its value for V
IN
= V

DC ELECTRICAL CHARACTERISTICS (continued)
(For devices with V
OUT
≤ 1.5V, V
IN
= 3.3V. For devices with V
OUT
> 1.5V, V
IN
= 5V. EN = IN, T

CRES
= 1000pF, unless otherwise noted. Typical values are at T
