Note 2: All devices are 100% production tested at T A = +25°C. Limits over the operating temperature range are guaranteed by
design.
Note 3: Resistors were added from OUT to CS+ to aid with power dissipation.
Note 4: Dropout is measured as follows:
Connect R O from OUT to CS+. Connect R SENSE = 2 ? (MAX16815) from CS+ to GND (for TDFN) or from CS+ to CS- (for
SO). Set V IN = 12V (record V OUT1 = V OUT ). For V IN = 40V, use R O = 360 ? ; for V IN = 6.5V, use R O = 56 ? .
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 5: Dropout is measured as follows:
Connect R O from OUT to CS+. Connect R SENSE = 1 ? (MAX16828) from CS+ to GND (for TDFN) or from CS+ to CS- (for
SO). Set V IN = 12V (record V OUT1 = V OUT ). For V IN = 40V, use R O = 180 ? ; for V IN = 6.5V, use R O = 27 ? .
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 6: I V5 = 0mA.
Note 7: 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 100 ? (MAX16815) or 51 ?
(MAX16828) from OUT to CS+.
Note 8: Current regulation varies with V5 load (see the Typical Operating Characteristics).
Note 9: Thermal shutdown does not function if V5 is shorted to ground.
