Note 1. Maximum positive supply voltage of 60V must be of limited duration (<100msec) and duty cycle(≤1%). The maximum continuous
Note 2. Full load current (I
Note 3. Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal value with V
Note 4. V
Note 5. Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current plus
Note 6. Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature range.
Note 7. Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied, excluding
Note 8. V
Note 9. Comparator thresholds are expressed in terms of a voltage differential at the Adjust terminal below the nominal reference voltage
