The SA21345S is an automotive grade, low-dropout voltage regulator for high input voltage and ultra-low quiescent current applications.
The SA21345S provides resistor adjustable output voltage with ±2% reference accuracy over temperature and 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 SA21345S is available in a compact SOP8E package.
