PRODUCTION DATA.
At low input voltages, the regulator drops out of regulation and the output voltage tracks input minus a voltage based on the load current (IO) and switch resistance (R(SW)). This allows for a smaller input capacitor and can possibly eliminate the need of using a boost convertor during cold-crank conditions.
