The EL7535 is a synchronous, integrated FET 350mA stepdown regulator in a MSOP10 package. The regulator is internally compensated, which makes it possible to use just five tiny external components to form a complete DC/DC converter. The regulator operates with an input voltage range from 2.5V to 6V, which accommodates supplies of 3.3V, 5V, or a Li-Ion battery source. The output can be externally set from 0.8V to VIN with a resistive divider.
