Controlled by a programmable digital power manager, the 14 user-programmable switched/linear regulators can be configured to meet the start-up sequence, voltage, and timing requirements for
most applications.

I expect that a customer could define the default startup voltages and power on sequence for their particular application. "37" would refer to a particular configuration. FWIW, that's the way that Active Semiconductor marks its PMICs.
