Hi team,

My customer is looking for an alternatives to replace with TPS7A8400.

And the LDO should have the similar Vin range, and 3A output current capability.

But the FB voltage…

Hi Team, 

just want to check how to set Vout to 0.8V if not using any-out function? Thanks.

Hello,

Can someone please provide the CTE for this component package? 

thank you

Dear team,

Except the output voltage range, is there any characteristics differences between ANY-OUTPUT and resister programming.

Like the transient response, power dissipation....etc

Best regards,

Dear BU friends,

Could we support TPS7A84 parallel to achieve 5A application. Customer prefer TPS7A84 due to the setting voltage is convenient for customer.

Hi team, 

I found that in datasheet, EN should be lower than VIN? What's the consideration here? Can custoemr pull up VIN to 1.8V and pull up EN to 3.3V？

Hi Teams,

My customer is using TPS7A84 which has Remote sns for ATE application. But the Iq of TPS7A84 is 2.8mA, which is too large for the system. Do we have low iq LDO parts to meet this requirement?

Hello Experts,

Refer Table 8.5 for feedback resistor values for setting the output voltage.

Can R1 be 6800 ohm and R2 vary from 30k ohm to 130 kohm (using a I2C potentiometer)? The resultant output voltage can change between 0.84V…

I would like to know what, if anything, I need to check to correct the output voltage of this regulator.

Vin is 5.1V

Vout = Vin = 5.1V .  ANY-OUT is configured for 3.3V.

The IC is configured identically to Figure 8-2 in the datash…

Hi team, 

may I know the operation of TPS7A84 when it’s output current exceeds the limitation? How TPS7A84 operates to protect the device from damage? And the protection is auto-retry or latchup? What the kind of overcurrent protection…

Hi Team,

ZTE uses TPS7A8401A, and they have some question when using this part.

Test condition: Vin=3.3V, Vout=2.5V, Iout=0.5A; RFB_up=30.1k, RFB_bottom=7.44k, cff=0.01uF

After the LDO normally outputs 2.5V, the load will have a reverse…

Hi,

Could you help share the accuracy of the feedback voltage? Thanks.

Hi team,

This is FAE Jayden, my customer use TPS7A8401, there is a fault that needs help to confirm:

Application: 3.6Vin~3.3Vout, Vout adjusted by using external FB resistors; When Vin power off…

Hi BU team,

What's the difference between TPS7A8300 and TPS7A8400? Which one do you recommend for powering the clock chip? Thanks.

Hi team,

The application I'm designing now is EMI demanding, so I'd like to reduce the noise as much as possible.

Question 1. Does charge pump noise appear on the VIN side as well?
Question 2. Is it better to use a ferrite…

Hi Team, 

Is there comparison between TPS7A53 and TPS7A57 and TPS7A84?  Thanks.

Hi team

this is my customer SCH  could you help me to review it ?

because I will LOA next week 

can you reply this week?

there are

Hi team,

I am Jayden, the customer I support used TPS7A8400RGRR. There is one thing need to be confirmed with team in application.

• When the TPS7A8400RGRR (3.6V to 3.3V ) is not working, there is a 1.3V voltage backflow at the output…

we buy the part#TPS7A8400ARGRR with date code year21 week05 ( 2105) & MSL LEVEL 2. But the MSL level is level1 showed in date sheet published in Sept 2021， and the it showed level 2 in data sheet published in Feb 2017, so could you…

Hi TI Team,

I have a question on TPS7A8300

We have power supply rail as above.

First of all the 1.5V is output from buck converter, and then ANALOG_0.9V is enabled before ANALOG_1…

Hi,

We are considering replacing TPS7A8300RGRT with TPS7A8400RGRT.

○ Output current… TPS7A8300 2A [Max], TPS7A84 3A [Max]

I think these two parts are pin compatible, but are they…

Hi Experts,

When looking at the LDO thermal resistance, they are the same between TPS7A83/84/85. Then how do i choose the LDO based on input/output voltage and current…
