PRODUCTION DATA
The device has an open-drain power-good pin, which is specified to sink up to 2 mA. The power-good output requires a pullup resistor connected to any voltage rail less than 5.5 V. The PG signal can be used for sequencing of multiple rails by connecting it to the EN pin of other converters. Leave the PG pin unconnected when not used. Table 8-1 shows the typical PG pin logic.
