NOTES:

A. Derived during test from the parameters DC

B. For specifications with negative values, a negative temperature coefficient corresponds to an increase in magnitude with

increasing temperature, and a positive temperature coefficient corresponds to a decrease in magnitude with increasing

temperature.

C. Guaranteed by characterization. Not tested in production.

D. For externally adjusted current limit values, please refer to Figures 34 and 35 (Current Limit vs. External Current Limit Resistance)

in the Typical Performance Characteristics section. The tolerance specified is only valid at full current limit.

F. The device will start up at 18 V

below 0 °C. For reliable start up at 18 V in sub zero temperatures, designers must ensure that circuit capacitors meet recom-

mended capacitance values.

G. Breakdown voltage may be checked against minimum BV

exceeding minimum BV
