The SD6303E50A with DC-DC Converters SOT23-3 RoHS is a DC-DC converter manufactured by SHOUDING. It is a miniature, 3-pin, SOT23-3 package-compatible switching regulator that provides a wide range of adjustable output voltage that is stable and ripple-free. It is a low dropout regulator, which means that it maintains regulation with input voltages that are only a few hundred millivolts above the Vout. The SD6303E50A has a low quiescent current, making it ideal for low-power applications. The device is RoHS compliant, making it safe for use in environmentally sensitive equipment.
