power supply of nrf51822

[Amit Varshney]

Hi, I'm designing a prototype which uses a 6V battery with nRF51822. According to the specs nRF51822 power supply ranges from 1.8V to 3.6V. Can you tell me how to reduce the 6V into lower one without consuming much current.

The best way to lower the supply voltage in an energy efficient manner is probably to use an external DC/DC buck converter.
