HI,
Which item can design in M.2 circuit?
We need LDO POWER for M.2 VIO_CFG 1.8V(nc) & 3.3V(low) switching for sideband signals.
Thanks

Hello Perry,
How about TPS7A20? See some device specs below:
Do you happen to have some Vin and Iout requirements? Or specific key attributes that are needed for switching sideband signals?
Or were you looking for a dual output device with a 1.8V and 3.3V rail?

hi,
We need 5V to 3.3V LDO, 100mA ~500mA,
TPS7A20 is high to drive the device

Hello Perry,
Thank you for the additional information. We do have LDO's where you drive EN Low to power the device. Since you have a 1.8V and 3.3V output, would you want a single dual output LDO or se two single output LDO's? I will provide both parts for you to make a decision.
Please look at TPS702 / TPS701 (Dual Output)
TPS777 / TPS778 (single output) - 750mA
TPS775 / TPS776 (single output) - 500mA
You might want to check out TPS780 , it has a Vset HIGH and Vset LOW for 3.3V and 1.8V usually for micro controllers. However, it is below your 500mA spec.
Hope this helps,
