    The SA21345CDFD is an automotive grade, efficient, precise low-dropout voltage regulator designed for high input voltage and ultra-low quiescent current applications.

    The SA21345CDFD provides adjustable output voltage and very low drop out (300mV at 300mA). It offers protection features including over-current protection, thermal shutdown, and stable operation with low ESR ceramic or tantalum capacitors due to the optimized internal compensation.

    The SA21345CDFD is available in a compact DFN2×2-8 package.
