The 8681L occupies a middle ground – better dropout than XC6206, lower IQ than LM1117, but not the absolute best in any single category.
If the 8681L has an EN pin and you leave it floating, the internal state is undefined. The device may remain off or oscillate. Always tie EN to VIN or a logic high. 8681l ic datasheet
If the 8681L is an LDO, the pinout will typically be: The 8681L occupies a middle ground – better
The IC operates using an , which provides high efficiency (typically >95%) during power conversion. Its primary role is to dynamically manage the power distribution between the system load and the battery. lower IQ than LM1117
