Part Number: TPS734 Tool/software: Hello for a new design I have to do a noise measurement. I found the application note SLYY076, "How to measure LDO noise" that is a great help for understanding.
Nevertheless, I have a question on the measurement.…
Part Number: TPS734 Hello,
The part I'm using is the TPS73401DDC. Page 8 of the TPS734 datasheet in the Feedback Capacitor Requirements section (on the middle right hand side) says:
The feedback capacitor, CFB, shown in Figure 21 is
required for…
Part Number: TPS734 Other Parts Discussed in Thread: TPS784-Q1 , TPS784 Hey team,
I had a customer that was looking at these two parts and doing a brief comparison of the two. They highlighted the difference in startup time specified between the two…
Part Number: TPS734 Hi team,
My customer designs this device and the package will be DDC.
But there is no board layout and Stencil Design figure in the datasheet, so could you provide them to me?
Or send complete datasheet to me as well?
I need…
Hi Neil,
You are on the right path. The AC Coupling capacitors that were used for that app note and for the majority of our noise measurements for the last few years was constructed using a large number of MLCCs (multi-layer ceramic capacitor). There…
Part Number: TPS734 Other Parts Discussed in Thread: LP5900 , Some regulators spec output noise as a proportion of Vout, such as noise (uVrms) = 11 x Vout. Other datasheets specify noise as an absolute number such as noise = 11 uVrms. Are the differences…
Hi Steve,
We have not tested TPS734 with that particular circuit; however, you can size your feedforward capacitor (Cfb in the datasheet) in order to provide a soft-start.
Any pin to pin device will also not have a NR/SS pin which is the pin that…
Hi Chris,
The ADS122C04 datasheet does discuss other implementations including 4-wire RTD in section 9.2.2.2.1 and demonstrated in figure 76 using a low-side reference. More combinations and details regarding various connection scenarios are in the…
Hi Pol,
If the enable function is not needed, EN can be directly tied to VIN. No input resistor is required.
If the enable function will be used, EN must remain at a voltage lower than or equal to VIN through the use of external sequencing or clamping…
Hi Ian,
Thanks for sending this over. Here are a few devices that may fit your requirements: TPS734, TPS735,LP2989, or TPS799.
If you are open to using adjustable-output LDOs then I'd really like to recommend the TPS7A90 which actually has a 10uF…
