Note 4:
The LTC1261L is guaranteed to meet specified performance from
0
°
C to 70
°
C and is designed, characterized and expected to meet these
extended commercial temperature limits, but is not tested at –40
°
C and
85
°
C. Guaranteed I grade parts are available, consult factory.
Note 5:
The LTC1261L-4 and LTC1261L-4.5 will operate with less than the
minimum V
CC
specified in the electrical characteristics table, but they are
not guaranteed to meet the
±
3.5% V
OUT
specification.
Note 1:
The Absolute Maximum Ratings are those values beyond which
the life of a device may be impaired.
Note 2:
All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to ground unless otherwise
specified.
Note 3:
The output should never be set to exceed V
CC
– 10.8V.
