nRF51822 internal LDO output pin

[Anton]

Hello,

I'm drawing schematic with nRF51822 internal LDO. I'm wondering what is the regulated LDO output from nRF51822. I need to connect that with peripherals in stable volatage. My power connection is as below.

3.7V Li-polly Battery < - > nRF51822 internal LDO < - > peripherals.

Thanks, Anton.

Martin: is possible to use 1.2 internal LDO as voltage reference for analog comparataor so ~few uA?

Yes, it is possible to use an internal 1.2V voltage reference. You can do this by configuring the ADC to use the 1.2V VBG internal reference voltage. Read Chapter 31, "Analog to Digital Converter (ADC)" in the Reference Manual to learn how to do this.
