https://devzone.nordicsemi.com/f/nordic-q-a/125392/nrf9151-vdd-ripple-specificationWhat is the permitted VDD ripple on the nRF9151? I see &quot; To minimize supply voltage ripple and suppress EMI coupling to and from nRF9151 VDD , keep supply network impedance at the VDD pin below 0.2 Ω from 10 kHz to 50 kHz.&quot; And the ripple must stayen-USTelligent Community 13Thu, 06 Nov 2025 13:05:51 GMThttps://devzone.nordicsemi.com/thread/553560?ContentTypeID=1Thu, 06 Nov 2025 13:05:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:159cae3e-9ad9-4cbd-a4b0-c556c1cc3fb3SwRa<p>Hi Jeff,</p> <p>The only constraint is that the VDD operating range should be 3.0V to 5.5V (this range also includes the voltage drop, ripples and spikes).&nbsp;T<span>he VDD voltage, including any ripple, must never drop below 3.0 V during operation.&nbsp;</span></p> <p><span>Regards,</span></p> <p><span>Swathy</span></p><div style="clear:both;"></div>
