Battery-Switchover Circuit Accommodates 3V Systems

Abstract: Portable systems often require operation from batteries or from a wall adapter. 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
