Note 1:
2:
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
