(1)

Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation using

Statistical Quality Control (SQC) methods. The limits are used to calculate TI's Average Outgoing Quality Level (AOQL).

(2)

Typical numbers are at 25°C and represent the most likely parametric norm.

(3)

Output voltage line regulation is defined as the change in output voltage from the nominal value due to change in the input line voltage.

Output voltage load regulation is defined as the change in output voltage from the nominal value due to change in load current. The line

and load regulation specification contains only the typical number. However, the limits for line and load regulation are included in the

output voltage tolerance specification.

(4)

Dropout voltage is defined as the minimum input-to-output differential voltage at which the output drops 2% below the nominal value.

Dropout voltage specification applies only to output voltages of 2.5 V and above. For output voltages below 2.5 V, the drop-out voltage

is nothing but the input-to-output differential voltage because the minimum input voltage is 2.5 V.

(5)

This specification has been tested for –40°C

conditions.
