Does bq24074 boost the battery load output to 4.2V?

I want to make sure that I understand Adafruit's products correctly. Is the bq24074 load out pin always fixed at 4.2V? Does this item do so via a builtin "boost" component?

From the product description: https://www.adafruit.com/product/4755
Load output is regulated to never be over 4.4V so it's safe for 3.3V regulators or 5V boost converters


And from the guide: https://learn.adafruit.com/adafruit-bq2 ... ut/pinouts
OUT - Regulated load output. This pin will provide a regulated output when the input voltage is below the over voltage protection threshold and above the regulation voltage. It will never be higher than 4.4V (but it may dip down to 3V or whatever the LiPo battery voltage is at, if USB/DC isnt plugged in)

There is no boost. Only regulation.
