ELECTRICAL CHARACTERISTICS (continued)
(V IN = V EN = +12V, C V5 = 0.1μF to GND, I V5 = 0, V CS- = 0V, V DIM = +4V, connect R SENSE = 0.58 ? between CS+ and CS- (Note 1).
T J = -40°C to +125°C, unless otherwise noted. Typical values are at T A = +25°C.) (Note 1)

Note 1: All devices 100% production tested at T A = +25°C. Limits over the operating temperature range are guaranteed by design.
Note 2: Resistors were added from OUT to CS+ to aid with the power dissipation during testing.
Note 3: Dropout is measured as follows:
Connect R O = 27 ? from OUT to CS+. Connect R SENSE = 0.58 ? from CS+ to CS-. Set V IN = +12V (record V OUT as V OUT1 ).
Reduce V IN until V OUT = 0.97 x V OUT1 (record as V IN2 and V OUT2 ). ? V DO = V IN2 - V OUT2 .
Note 4: I V5 = 0mA.
Note 5: t ON time includes the delay and the rise time needed for I OUT to reach 90% of its final value. t OFF time is the time needed
for I OUT to drop below 10%. See the Typical Operating Characteristics. t ON and t OFF are tested with 13 ? from OUT to CST.
Note 6: Current regulation varies with V5 load (see the Typical Operating Characteristics).
Note 7: Thermal shutdown does not function if the output of the 5V reference is shorted to ground.
