Note 1 . Specifications are tested for production at T_A = 25ºC . Specifications over the -40ºC to 85ºC operating
temperature range are assured by design, characterization and correlation with Statistical Quality Controls (SQC).
Note 2. V_OS offset is the voltage measurement defined as V_OUT subtracted from V_REF.
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. In order to safely operate your system, V_CTRL must be > V_IN.
