TPS65988: Run off internal 3v3 LDO at all times.

Ben Riley

Part Number: TPS65988

I have a device that does not have a 3v3 rail. Is it fine to run the TPS65988 off the internal 3v3 LDO at all times?

Hi,

LDO_3V3 has a current limit. What is the current consumption of the device?

It will only have a flash chip drawing ~10 mA max on the rail. Below the stated 25mA the LDO is capable of.

Hi,

You will also need to consider current consumption pull ups that are pulled to LDO_3V3. As long as it does not crash LDO_3V3 it should be fine.
