(1) Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation using
Statistical Quality Control.
(2) Typical numbers are at 25°C and represent the most likely parametric norm.
(3) Long-term stability is V_REF at 25°C measured during 1000 hrs.
(4) Thermal hysteresis is defined as the change in 25°C output voltage before and after cycling the device from (–40°C to 125°C).
(5) Dropout voltage is defined as the minimum input to output differential at which the output voltage drops by 0.5% below the value
measured with a 5-V input.
