Powering NRF24l01+ with DC-DC Module Abaisseur Regulateur Tension Step Down

[Snyfir]

Hello everybody,

When i powered nrf24l01+ with this module or this one the nrf24l01+ is not working (unable to send / received).
But if i use https://www.ebay.com/itm/200960749614 the same nrf24l01+ works perfectly.
All regulator deliver 3.3V so i don't know why it doesn't work. The input DC is 12V for all

Do you have a clue ?
Thank you for your help.

As i see, two first module is impulse, but third - linear?

[Snyfir]

Yes two first modules are switching regulator an the third is linear.
Nrf24l01+ are not compatible with switching regulator ?

@snyfir a switching regulator (at least the cheap ones) does not deliver as stable power as a linear regulator. The nrf24 is extremely sensitive to unstable power.

@mfalkvidd
I want to use a switching regulator ta avoid too lost of current and heat (12v to 3.3V). A LC filter can solve my issue ?

I am use switching DC-DC the same as you to get 5V from 12V and LDO XC6206 to power NRF24 module - all work good.
