Tool/software:

I am reaching out regarding a design challenge in my application and would appreciate your assistance…

Tool/software:

I am looking for a low-noise LDO that can output 5V at a 4A load and handle an operating temperature of -55°C. I came across the TPS715401. However, I am confused about the difference…

Tool/software:

Hi Team,

The TPS7A91 datasheet shows that when VFB reaches 97% VREF, INR/SS is turned off and VNR/SS is charged through RNR. For TPS7A54, what is the switching voltage? Is it…

Tool/software:

We use TPS7A5401QRGRRQ in our current design.

Could we use TPS7A8500ARGRR instead of TPS7A5401QRGRRQ1 without any change schematic/layout?

Thanks,

Jimmy Huang

Hi Team,

Customer report the vout waveform is abnormal when pull the enable low. Pls check the waveform and schematic below. As double check with customer the test method is good. Do you have any comments for this case?

Hi, teams.

I wan to calculate the discharge time.

According to DS, there is resistor for active discharge in TPA7A54 and it is desribed as "several hundred ohms".

Can you provide specific…

Hi Team,

We are using 2 ADC12DJ5200 for 4 Channel 

I've few questions on power supply regulator + LDO vs Silent…

Hello expert,

I checked on E2E forum and see we have a requirement that VBIAS needs to be stable before VIN.  But do we have requirement for the timing? like VBIAS needs be stable for how long then VIN can start up? Thanks!

Hi Experts

datasheet tell us.  bias can improve dc and ac performance 

I wonder how does bias work to improve it.

Hi,

Good Day.

If LP3856ES-2.5/NOPB (2.5V/3A) recommended for Voltage rail to an FPGA device?

Please advise. Thank you very much.

Hi team, 

I am using the TPS7A54 and with the 5V power supply on the bias pins. I find in data sheet section 7.3.2.2. There is a description that bias is better not change when VIN>1.4V. Does that means the bias voltage should be ready…

Hi,

I noticed that the TPS7A5401RPST is a VQFN package. But what is the material of the Bond Wire of TPS7A5401RPST? Thanks.

Hi team!

I see TPS7A54 parallel method on the link( https://e2e.ti.com/support/power-management-group/power-management---internal/f/power-management---internal-forum/1052479/tps7a54…

Dear team,

We would like to calculate device output accuracy for system design. But cannot find min/max value of VFB.

Does Vout accuracy in datasheet exclude feedback…

Dear Sirs,

May I use 2 LDOs in parallel to get a double output current?

My customer wants to use 2pcs TPS7A7401 to do such design.

Please help to advise.

Thanks.

Hi team,

My customer is considering TPS7A54 to generate 2.3V/15A from 2.5V rail by current sharing configuration.

The available rail is limited, so I think they will go without BIAS.

Just for reference, if BIAS is used, is clean power…

Hi all,

Customer was wondering how ferrite beads on the bias input affect Vout noise and PSRR? Does it impact it at all?

Thanks,

Dear TI,

I am currently using TPS7A5201RPST, for my design. The design is ready for production unfortunately I couldn't get hold of this part both from the supplier or Mouser. Question…

Hi team,

Due to the constrained supply of TPS7A8300, we recommended TPS7A8400. However, its supply is still tight. From this thread, TPS7A7200…
