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”.
