The Maxim Integrated MAX738ACWE+T is a step-down (buck) switching regulator that delivers a fixed 5V output at up to 750 mA from an input rail between 6V and 16V. Switching at 160 kHz, it uses an external diode and inductor — no synchronous rectifier inside, so the bill of materials includes a Schottky catch diode. The 16-SOIC wide-body package (7.50 mm width) suits medium-density boards where a TO-220 or D2PAK would be overkill.
The 750 mA output current is the continuous rating. The 160 kHz switching frequency calls for a larger inductor than a higher-frequency part.
It is ROHS3 compliant, which clears the REACH and RoHS paperwork for EU-bound builds.
