Other Parts Discussed in Thread: UA78
Team,
The datasheet mentions the UA7805 as possible LDO option but it is not available in 3.3V.
It is not 100% sure but the options could be:
DVDD 3.3V and AVDD 5V
or
DVDD/AVDD 3.3V
The assumption is that the Vin for the LDO would be between 7V and 5V.
-What low cost alternative to UA7805 do you recommend for 3.3V?
Here is a TI.COM comparison table.
What do you recommend from this table?

-SBAS523D page 8 gives 117mW as highest power consumption.
Is it truly the worth case scenario under the condition listed?
Is for example the power up higher than this? What extra power margin would you recommend for the supply?
Thanks in advance!
