The MAX8865 low- dropout (LDO) linear regulator is used to provide the switchover function while supplying a regulator 2.84V that can deliver 100mA. Portable systems often offer the flexibility to operate either from an internal battery or from an ac-to-dc wall adapter. Many such systems include circuitry that switches automatically between the internal battery and an external source as the user connects and disconnects the wall ad……
