Part Number: TPS7A49 We had one TPS7A4901DGNR fail on one of our products and our customer has asked us to identify if there is any known errata or failure issues associated with this part. Is there any such information associated with the TPS7A4901DGNR…
Part Number: TPS7A49 Hello, I'm an NCG FAE from China, I tested the transient of LDO EVM and got this diagram, I wonder why there is a voltage gap between stage1 and stage2.
the yellow curve is the current load, and the pink curve is the output voltage…
Part Number: TPS7A49 Hi,
We are using a TPS7A4901 IC (DRB package) to generate a 30V regulated output from a 32V supply. The circuit is provided as given below
The 32V power supply is provided by a DC source with current limit set to 100mA.
We are facing…
Part Number: TPS7A49 Hello,
The datasheet recommends that VIN ≥ VOUT(nom) + 1 V. However, under normal operation in section 8.4.1 it lists one of the modes as: The input voltage is greater than the nominal output voltage added to the dropout voltage…
Part Number: TPS7A49 When the TPS7A49 EVM NR/NSS is grounded, the output voltage is 0.
The chip manual explains the Colum to soft-start, so why is it not possible to start if it is grounded?
What's more, when i changed the input vlotage from 7V to 10V…
Part Number: TPS7A49 Hello, Post
I supply the TPS7A49 device with an unregulated iso-converter.
The device, when unloaded, will drift up significantly from the 16.5V nominal and almost hit 40V. This exceeds the maximum datasheet Vin to GND but only…
Part Number: TPS7A49 Other Parts Discussed in Thread: IVC102 , LM27762 , , TPS7A30 , TPS7A94 Hi Team,
This inquiry is related to the other thread below. Our customer is looking for a low noise power supply for IVC102 precision transimpedance amplifier for a…
Part Number: TPS7A49 Hello, I have a challenge about the phenomenon that occurred during experiment.(Vin = 5.5V , Vout= 5V)
I tried to find the difference when i change soft start capacitor. And the experiment was successful.
However there were some happening…
Part Number: TPS7A49 Hi Team,
May I know TPS7A4901DRBR package information? datasheet only show DGN information but no DRB.
and package information link only show one page with package picture.

Please help…
Part Number: TPS7A49
We want to confirm that the VSON exposed pad land pattern should be as shown on page 30 of the datasheet.
There are conflicting pictures of the bottom of the IC on pages 28 and 29. Additionally, when we use the link for the SON …
