ELECTRICAL SPECIFICATIONS
MIN and MAX limits are valid for the recommended ambient temperature range of -40°C to 85°C. Typical values represents
statistically the utmost probability at following conditions: V

NOTES
(1) Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed
through correlation using Statistical Quality Control (SQC) methods.
(2) Typical numbers are valid at 25°C ambient temperature and represent statistically the utmost probability assuming the
Gaussian distribution.
(3) Depending on load current, see derating diagram
(4) Measured without heatsink, no air flow
(5) The industry standard for comparison of the output voltage ripple between switching regulators or modules requires a
10µF ceramic (sometimes additional 1µF ceramic in parallel) at the point of load where the voltage measurement is
done using an oscilloscope with its probe and probe jack for low voltage/high frequency (low impedance) measurement.
The oscilloscopes bandwidth is limited at 20MHz.
