7.2.9 Regulators
The regulator block offers a 5-V LDO and a 3.3-V LDO. The VCC LDO regulates VB down to 5 V with an external
PNP controlled by the regulator block. The 5-V LDO is supplied to the MCU and other components. The 5-V LDO
is protected against a short to GND fault, and the external resistors R1 and R2 set the undervoltage. The VDD
regulator regulates VB down to 3.3-V with an internal FET and a controller.
The regulators detect the overvoltage and undervoltage events of both supplies.
