Reserved.

REG4

0x50

[5:0]

VSET

R/W

Output Voltage Selection. See the Output Voltage Programming

section for more information.

REG4

0x51

[7]

R/W

Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to

0 to disable the regulator.

REG4

0x51

[6]

DIS

R/W

Output Discharge Control. When activated, LDO output is 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.

REG4

0x51

[5]

LOWIQ

R/W

LDO Low-IQ Mode Control. Set bit to 1 for low-power operating

mode, clear bit to 0 for normal mode.

REG4

0x51

[4:2]

DELAY

R/W

Regulator Turn-On Delay Control. See the REG4, REG5, REG6,

REG7 Turn-on Delay

section for more information.

REG4

nFLTMSK

R/W

Regulator Fault Mask Control. Set bit to 1 enable fault- interrupts,

clear bit to 0 to disable fault-interrupts.

REG4

0x51

[0]

Regulator Power-OK Status. Value is 1 when output voltage exceeds

the power-OK threshold, value is 0 otherwise.
