Application Block for Power Tool

The battery-powered power tool has an MCU that is always running. The power tool is used only a few times a year and the battery will run out if not used for a long time. Then you have to wait for the charging time and the user will feel stressed. However, RICOH's LDO consumes less, so the battery will not run out even if left for a long time.
