Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
The LTC1682C is guaranteed to meet specified performance from
0
°
C to 70
°
C and is designed, characterized and expected to meet these
extended temperature limits, but is not tested at –40
°
C and 85
°
C. The
LTC1682I is guaranteed to meet the extended temperature limits.
Note 3:
Dropout voltage is the minimum input/output voltage required to
maintain regulation at the specified output current. In dropout the output
voltage will be equal to: V
CPO
– V
DROPOUT
(see Figure 4).
Note 4:
Operating conditions are limited by maximum junction
temperature. The regulated output specification will not apply for all
possible combinations of input voltage and output current. When
operating at maximum input voltage, the output current range may be
limited. When operating at maximum output current, the input voltage
range may be limited.
Note 5:
Limited by the LDO disable switch point of 1.45V
IN
.
Note 6:
The LTC1682 is set to 5V. The feedback current is 25
