Part Number: TPS7A84A Dear expert,
My customer is using TPS7A8400A to develop a low-noise, high-accuracy LDO, as shown in the figure. It is 3.3V ~ 5V input, 3.3V fixed voltage output, load current starts 2.5A, stable 0.9A.
There are also several uncertain…
Part Number: TPS7A84A Other Parts Discussed in Thread: TPS7A84 Hey
For Xilinx RFSoC Power Rails, Xilinx recommend in there PCB design guide (UG583), to use the Intersil/Renesas ILS80101-A/ ILS80102/ ILS80103/ low noise high PSRR LDOs.
can the TPS7A84A be…
Part Number: TPS7A84A Hi Team,
Here is a question from customer that they put 3x 2.2nf=6.6nf cap on NR/SS pin but datasheet recommend 10nf to 1uf. So just want to check the effect.
To my understanding, if Vout start up normally and noise on Vout can be…
Part Number: TPS7A84A Hi Team,
I am working on a reference design board for a high-speed device and would like to use the TPS7A84A to provide my supply rails. I will be taking 3.3V from a lab supply and supplying 2 rails for my device. Depending on the…
Part Number: TPS7A84A Other Parts Discussed in Thread: TPS7A85A , , TPS7A52 , TPS7A84 I am currently looking at my options for filtering out some 900KHz supply ripple using an LDO. The application requires that the LDO be able to source >= 2.2A (>3A preferred…
Part Number: TPS7A84A Hi,
I have a question on how to measure TPS7A8400 LDO noise density spectrum. As can shown in the datasheet, the unit of the curve is uV/sqrt(Hz). how to measure it, does the spectrum meter has the noise density spectrum function…
Part Number: TPS7A84A The TPS7A84A datasheet specifies all output performance parameters (output voltage accuracy, line regulation, load regulation) from 5mA < Iout < 3A. Under Recommended operating conditions it lists output current as 0 to 3A. Is the…
Part Number: TPS7A85A Hi Experts, I want to control the Any-Out pins of this LDO using FPGA LVCMOS IO or I2C expander. What are the VIH and VIL levels for this pin to pull it to ground and keep it open.
