bandgap and the rest of the core circuitry is supplied from VCORE. The performance of the regulators is directly dependent on
the performance of VCOREDIG and the bandgap. No external DC loading is allowed on VCOREDIG or REFCORE. VCOREDIG
is kept powered as long as there is a valid supply and/or coin cell.

This section describes the linear regulators provided. For convenience, these regulators are named to indicate their typical or
A low power standby mode controlled by STANDBY is provided in which the bias current is aggressively reduced. This mode
Some dedicated regulators are covered in their related chapters rather than in the Supplies chapter (i.e., the VUSB and VUSB2
Apart from the integrated linear regulators, there are also GPO output pins provided to enable and disable discrete regulators
All regulators use the main bandgap as the reference. The main bandgap is bypassed with a capacitor at REFCORE. The

The core is in On mode when charging or when the state machine of the IC is not in the Off mode nor in the power cut mode. Otherwise,
the core is in Off mode.
