(1)

Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation

using Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality Level (AOQL).

(2)

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

(3)

VREF measured in a non-switching, closed-loop configuration.

6.5 Electrical Characteristics

All Typical specifications are for TJ = 25°C only; all Maximum and Minimum limits apply over the operating junction

temperature range TJ range of –40°C to 125°C. Minimum and maximum limits are ensured through test, design, or statistical

correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes

only. AVIN = PVIN = EN = 5 V, unless otherwise indicated in the Test Conditions column.
