Guys-- Thank you so much for your recommendations! This is helpful! I shall review all the recommended components and let you know how I proceed.

Thanks again! P.K.

I'm using LTC3554 in a design with the nRF1822 and generally like it . Be aware that datasheet has some confusion around how to disable the NTC thermistor -- see the example board circuit -- you need a pair of resistors.

Alternatively, if your application is cost-constrained (Linear parts don't come cheap), a generic footprint LDO in sot23-5 is a sensible option (like TPS76433DBVT). Of course you'll have to check the datasheet yourself to make sure that the specs are appropriate for your actual circuit design :)

For high efficiency at low currents, you might also want to look at the LTC3388:

Take a look on this part

LTC3554

Is a very good candidate

Hi,

We do not use many LDOs in our reference designs, so it's hard to recommend any regulators from our side. If your other peripherals needs 3.3V, I would just go with a LDO that has a set output of 3.3V. These can be found at any regulator manufacturer.

Best regards Håkon
