Consult factory for parts specified with wider operating temperature ranges.
ELECTRICAL CHARACTERISTICS The q denotes specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VCC = 4.5V to 5.5V (LTC1657), VCC = 2.7V to 5.5V (LTC1657L),
VOUT unloaded, REFOUT tied to REFHI, REFLO tied to GND, X1/X2 tied to GND, unless otherwise noted.
