TCAN4551-Q1: With or without LDO

Part Number: TCAN4551-Q1
Other Parts Discussed in Thread: TCAN4550-Q1, TCAN4550

Dear team,

I have a question about TCAN4551-Q1 that need your support.

I found that on Ti.com, it says that TCAN4551-Q1 is without LDO and the TCAN4550-Q1 has LDO.

However, in the datasheets of TCAN4551-Q1 and TCAN4550-Q1, both show that have LDO inside.

The screenshot is shown as below:

Could you please help me to confirm whether TCAN4551-Q1 has LDO and what is the difference between TCAN4550-Q1 and TCAN4551-Q1?

Really appreciate your help and support!

Best regards,

Xenon Li
