PRODUCTION DATA.
The fuel gauge has an integrated LDO with an output on the REG18 pin of approximately 1.8 V. A capacitor of at least a 2.2-µF value should be connected between the REG18 pin and VSS. The capacitor must be placed close to the fuel gauge and have short traces to both the REG18 pin and VSS. This regulator must not be used to provide power for other devices in the system.
