Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: The LTC1503C is guaranteed to meet specified performance from

°C to 70°C and is designed, characterized and expected to meet these

extended temperature limits, but are not tested at – 40

°C and 85°C. The

LTC1503I is guaranteed to meet the extended temperature limits.

Note 3: Currents flowing into the device are positive polarity. Currents

flowing out of the device are negative polarity.

Note 4: When VOUT is less than 150mV, IOUT is limited to much less than

the maximum rated output current to prevent damage to the output

devices.
