The Bold specifications applying to the over full operating temperature range.
Note 1: Low duty cycle pulse testing with Kelvin connections are required to order to maintain accurate data.
Note 2: Dropout voltage is defined as the minimum differential between VIN and VOUT or VCTRL and VOUT required to maintain regulation at VOUT
99% Nominal VOUT.
Note 3: VREF is measured across Adjust pin to Sense pin.
