Part Number: LP3907 Hi,
Could I just keep the unuesd PIN on LP3907 floating? or do you have a better recommendation for the unused PIN? Do I need to pull up to connect them to the ground?
NOTE： X means unused.
Part Number: LP3907 Hi Team,
For VINLDO1 and VINLDO2, what is the minimum input capacitance specified for the device? I found this information for the switching power supplies, but do not see it for the LDOs.
Thank you for your support!
Jared
Other Parts Discussed in Thread: LP3907 , LP3907-Q1 I cannot find datasheet of LP3907-Q1 on TI website and only find calalog LP3907 datasheet. Is there any datasheet difference between LP3907 and LP3907-Q1? Thanks!
Hi Artur,
I apologize for the misleading content. I'll see if we can have this revised to avoid any confusion in the future.
In this case, then yes, I would recommend something like the TPS65000 or TPS65000-Q1 here.

Hi Albert,
Unfortunately, this is an older device with limited support for new output voltage settings. Is it possible to consider the LP3907 for this application? This is a newer version of the PMIC with I2C programmability to configure the buck and…

Hello Frank,
We have one PMIC with a buck-boost, TPS65218. It has 5 bucks, 1 buck-boost, and 1 LDO. Based on your requirements, it may not exactly fit what you are looking for.
Another option would be to use a separate buck-boost front-end regulator…
