DESCRIPTION
R Reserved.
R/W
Output Voltage Selection. See the Output Voltage
Programming section for more information.
R/W
Regulator Enable Bit. Set bit to 1 to enable the regulator,
clear bit to 0 to disable the regulator.
Output Discharge Control. When activated, LDO output is
R/W
discharged to GA through 1.5kΩ resistor when in shutdown.
Set bit to 1 to enable output voltage discharge in shutdown,
clear bit to 0 to disable this function.
R/W
LDO Low-IQ Mode Control. Set bit to 1 for low-power
operating mode, clear bit to 0 for normal mode.
R/W
Regulator Turn-On Delay Control. See the REG4, REG5,
REG6, REG7 Turn-on Delay section for more information.
R/W
Regulator Fault Mask Control. Set bit to 1 enable fault-
interrupts, clear bit to 0 to disable fault-interrupts.
R
Regulator Power-OK Status. Value is 1 when output voltage
exceeds the power-OK threshold, value is 0 otherwise.
