TLE4275-Q1: TLE4275 is screaming

Hi Amelie,

I think the linear regulator is possibly unstable, but I cannot make out the information on the capacitors to know for sure.
I need the following information:

C60, C61, C62, C64, C65, C71 manufacturing part numbers.
Or, the capacitance value, voltage rating, and ESR. 
But it is better to give me the manufacturing part numbers so I can look up the models on the manufacturer's website.

Also, part numbers for R58 and R60 should help.
I will assume they are zero ohm resistors and can have an actual resistance of 20m ohms max, unless I have the part numbers.

Alternatively, the customer can review the load themselves and compare it against the data from figures 16 and 17 in the datasheet.

Thanks,

- Stephen

Hi Stephen,

Thanks for your reply. I will ask customer to change the Cap or series a little resistance to have a try to change ESR.

May I ask do we have recommendation about replacing TLE4275-Q1? This socket is quite old. Customer also wants to update it in new project.

Thanks!

Just to add customer's requirement: 12V to 5V, Vin=7-24V,Iout=500mA.

I think TPS7B68-Q1 is also OK for their requirement.

Do you think which idea is better:

• Continue to use TLE4275 
• Change to TPS7B58-Q1

Hello Amelie,

Do they need a reset function or can they use a part like TPS7B81-Q1 instead? If they need the reset functionality, TPS7A66-Q1 is another option.

Hi Aaron,

Thanks for your reply.

I think TPS7B81-Q1 and TPS7A66-Q1 may be not suitable for customer.(They need 450mA output current at least.)

 Do you think it is suitable to promote TPS7B68-Q1?

Actually customer also want to know whether TLE4275 will suspend production or EOL within 2-5 years? Could you give an answer?

Thanks！

Hi Aaron,

Thanks for your reply!

As customer output current requirement is at least 450mA, I think TPS7B81 and TPS7A66 may be not suitable for them.

What about promoting TPS7B68-Q1?

Actually customer want to confirm whether TLE4275 will suspend production (EOL) or nor within 2-5 years? Could you give an answer about this？

Thanks!

Hello Amelie,

Yes, TPS7B68-Q1 could work here too.

There are no plans for EOL for the TLE4275-Q1 at this time.
