Note 1:

Specifications are production-tested at T A=25°C. Specifications over the -40°C to 85°C operating

temperature range are assured by design, characterization and correlation with Statistical Quality

Controls (SQC).

Note 2

: VOS is the difference between VOUT and VREF.

Note 3

: Load regulation is measured at constant junction temperature, using pulse testing with a low duty cycle.

Note 4

: Current limit is measured using a low duty cycle.

Note 5

: To operate safely, VCNTL must always be greater than VIN.
