Hello Poki,

I think answer is yes. You can look at this previous case (13) nPM1300 LDO Registers vs LDSW Registers - Nordic Q&A - Nordic DevZone - Nordic DevZone.

Hi Kazi:

Could you help check LDSWCONFIG soft start also can apply on LDO mode?

Thank you

Poki

Hello Marks,

I got rely from team.

LDSW1GPISEL should allow to control the component regardless of the mode (this is not tested yet) even though it says "Load Switch" in the description.
LDSWCONFIG: discharge seems to apply to both modes

Hello Markus,

'' Register 0x00 with name TaskLDSW1Set: Enable LDSW1. After some testing my understanding is that even though the name and description of the register only mentione the load switch, it can be used for both load switch and ldo to be enabled. Can registers 0x00 and 0x01 be used to enable the output of the regulator independ of the mode (load switch & ldo)? ''

These two registers can be used for enabling the output of the regulator independent of the mode. It's mentioned in the product documentation.

"The load switches can be separately configured as LDOs. The output voltage is configurable in registers LDSW[n]VOUTSEL.''

For rest of the two questions, I have asked team. I will get back to you soon.

Thanks.

Kazi
