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: DDR2 is not available for TO-263 package.
Note 3: V
OS
is the voltage measurement, which is defined as V
OUT
subtracted V
REF.
Note 4: Load regulation is measured at constant junction temperature, using pulse testing with a low ON time.
Note 5: Current limit is measured by pulsing a short time.
Note 6: For operate system safely; V
CNTL
must be always greater than V
