Typical Application


The SY20728B is a 3A high current capacity and low drop out voltage regulator, which features very fast transient recovery from input voltage surges and output load current changes. The SY20728B has an adjustable output which can be set by two external resistors to a voltage between 1.24V to 18V. SY20728B with fully protection includes over current limit, and over temperature operation.
