Temperature Coefficient
(1) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using Statistical
Quality Control (SQC) methods. The limits are used to calculate Average Outgoing Quality Level (AOQL).
(2) Dropout voltage is defined as the input to output differential at which the output voltage drops 100 mV below the value measured with a
1V differential.
(3) See Typical Performance Characteristics curves.
(4) Temperature coefficient is defined as the maximum (worst-case) change divided by the total temperature range.
