Notes:
1/ Specification derated to reflect Total Dose exposure to 100 Krad (Si) @+25°C.
2/ Dropout results from either minimum control voltage, VCONTROL, or minimum input voltage, VIN, both specified with respect to
VOUT. These specifications represent the minimum input-to-output differential voltage required to maintain regulation.
3/ Pulsed @ <10% duty cycle @ +25°C for characterization only.
4/ Not tested. Shall be guaranteed to the specified limits.
