General Description
The SY20704 is a high input voltage, low-ground current,
low-dropout voltage regulator capable of sourcing 150mA
with only 300mV of dropout. The SY20704 wide inputvoltage range supports operation as low as 2.3V and up
to 30V. It provides a resistor programmable output voltage
with ±2% accuracy over temperature.
The SY20704 provides protection features including logic
enable control, thermal shutdown, current limit, and
reverse leakage current protection for reliable operation.
Its internal compensation enables stable operation using
low ESR ceramic capacitors. The device also provides
reverse input voltage protection up to -20V Abs. Max.
The device is suitable for use in multiple consumer and
industrial applications.
The SY20704 is available in SOT23-5 or DFN
2mm×2mm-6pin packages.
