Typical Application


The SY20704 is a 150mA precise LDO. The device provides programmable output voltage with +/-2% accuracy. The ultra low drop out voltage, wide input voltage range and low ground current make it suitable for USB and portable electronics applications with different inputs. Other features include the operation stability with low ESR ceramic capacitors due to the internal compensation, logic enable control, thermal shutdown, current limit, reverse leakage current protection.

The SY20704 is available in SOT23-5/DFN2×2-6 package.
