Temperature Range
Thermal shutdown temperature 165 ºC TSD Thermal shutdown hysteresis 15 ºC (1) Dropout voltage is the minimum input to output voltage differential needed to maintain regulation at a specified output current and measure for VOUT(NOM) ≥ 1.8V. In dropout, the output voltage will be equal to: VIN – VDROPOUT.
