Typical Application


SY20725 is an efficient, precise LDO designed for high input voltage and ultra low quiescent current applications.

SY20725 provides adjustable output voltage with +/-2% accuracy and very low drop out (300mV at 300mA). Other features include the operation stability with low ESR ceramic or tantalum capacitors due to the optimized internal compensation, over current protection and thermal shutdown.

SY20725 is available in SOT23-5 package.
