It is designed to operate from a single input supply with an input voltage as low as 1.10 V, without the requirement of an external bias supply, to increase efficiency and provide up to 2 A of output current. The low 62 m V typical dropout voltage at a 2 A load allows the ADP1762 to operate with a small headroom while maintaining regulation and providing better efficiency. Rev.
