_______________________________________________________________________________________
Note 2:
All devices are 100% production tested at +25
°
C and are guaranteed by correlation for T
A
= T
MIN
to T
MAX
.
Note 3:
Guaranteed by design.
Note 4:
Dropout voltage is defined as (V
IN
- V
OUT
) when V
OUT
is 2% below the value of V
OUT
for V
IN
= V
OUT(NOM)
+ 1V.
Note 5:
MAX6473/MAX6474/MAX6481/MAX6482 are guaranteed by design for V
OUT
< 2.5V.
Note 6:
Select the reset timeout period using the
Reset Timeout Delay Guide
(Table 3). Insert the appropriate suffix in the part number
when ordering.
