Part Number: TPS7B4255-Q1 Other Parts Discussed in Thread: TPS7B4254-Q1 Hello
Would it be possible for you to provide the SPICE model for device TPS7B4255-Q1?
Part Number: TPS7B4255-Q1 We are going to use this tracker in our new design for supplying off-board sensors. Is this tracker able to survive to 24V - Load Dump pulse test (the pulse reaches 58V for 300ms)?
If the answer is no, do you have any other…
Part Number: TLV4110 Other Parts Discussed in Thread: TPS7B4255 , INA826 , OPA994
Tool/software:
Hello,
I need to supply an adjustable voltage 1.7-2.7V to a PCB at end-of-line test, 3.6VAbs Max. This will come from an offboard bench supply but I…
Part Number: TPS7A90 Other Parts Discussed in Thread: TPS7B4255 Tool/software: I want to use the TPS7A90 for an external 5V signal that protects the output from up to 16V shorts condition. Is there a spec for the max injection current of the FB pin?
Part Number: LM317 Other Parts Discussed in Thread: DAC80508 , TPS7B4255-Q1 Hello,
I would like to have some informations on this LM317.
The point of the project is to have on the input of the regulator 5V and to have an ouput between 1.5v and 5V…
Hi Tasneem,
How about using a tracking LDO, something like https://www.ti.com/product/TPS7B4255-Q1 , with a resistor + cap divider from VIN -> ADJ/EN -> GND?
It won't be a linear delay, but using a 20k resistor + 0.1uF cap for example should give…
Hi Zehui,
Yes , as long as the voltage provided at the ADJ/EN pin is within the recommended datasheet values, it does not matter if the voltage is provided by a dedicated voltage reference, MCU GPIO, battery, etc.
Just note that the LDO output will…
Hey Adrian,
This does not seem like a stability issue because the part is not oscillating.
This might be caused by the internal soft-start circuitry. The part could be starting up faster than the internal circuitry allows.
After speaking with colleagues…
