Typical Application


The SY20703 is a 3A current capacity and low drop out voltage regulator, which features very fast transient recovery from input voltage surges and output load current changes. The SY20703 has an adjustable output which can be set by two external resistors to a voltage between 1.24V to 29.6V. The SY20703 with fully protection includes over current limit, output short protection, over input voltage protection and over temperature operation.
