† 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

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.

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”.
