Note 1: Specifications are production tested at TA=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 voltage measurement, which is defined as VOUT subtracted VREF.
Note 3: Load regulation is measured at constant junction temperature, using pulse testing with a low ON time.
Note 4: Current limit is measured by pulsing a short time.
Note 5: For operate system safely; VCNTL must be always greater than VIN.
