† Notice: Stresses above those listed under “Absolute
Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of
the device at those or any other conditions above those
indicated in the operational listings of this specification is not
implied. Exposure to maximum rating conditions for extended
periods may affect device reliability.

Note 1: Output temperature coefficient is measured using a “box” method, where the +25°C output voltage is trimmed as close
to typical as possible. The 85°C output voltage is then again trimmed to zero out the tempco.
2: Output Voltage Hysteresis is defined as the change in output voltage measured at +25°C before and after cycling the
temperature to +85°C and -40°C; refer to Section 1.1.10 “Output Voltage Hysteresis”.
