I'm designing my own pcb with a IMU and nRF51422 but i confused,
What's the best choice, LDO, DC-DC or external regulator configuration if I'll use a cell coin?
Someone said that use a external regulator is better for save power consumption and in cases that the battery life is factor, but increment the price. --> devzone.nordicsemi.com/.../
Other issue is that the dc-dc have some troubles with softdevices.
Other issue is that the J'LINK need 3.3 Volt for program the target and in other question that I read that the best functionality for nrf51 is at 1.8V, so?
I have a mess, I hope someone can help me
Thanks!
