ELECTRICAL CHARACTERISTICS

The q denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C.

VCC = 2.7V to 5.25V, C1 = CCP = 0.1µF, COUT = 10µF, TA = 25°C unless otherwise specified. (Note 3)

Note 1: 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. All typicals are given at TA = 25°C.

Note 3: The LTC1550LC/LTC1551LC are guaranteed to meet specified

performance from 0°C to 70°C and are designed, characterized and

expected to meet these extended temperature limits, but are not tested at

– 40°C and 85°C. The LTC1550LI is guaranteed to meet the extended

temperature limits.
