Part Number: TPS7A14 Other Parts Discussed in Thread: TPS7A10 , TPS7A11
Page 1 of the TPS7A14 datasheet says:
Available in fixed-output voltages: – 0.5 V to 2.05 V (in 25-mV steps)
However table 11.1.2 describes the device nomenclature as TPS7A14xx…
Part Number: TPS7A14 Hi Team,
As per the datasheet of TPS7A14, IQ(Bias) at Iout-1A is 12mA.
We have checked the same with TPS7A14EVM-058 EVM , in EVM VBias pin is taking 100mA from 3.7 supply (Vbias voltage) and we are not getting exact 1.3V at Vout.
we…
Part Number: TPS7A94 Other Parts Discussed in Thread: TPS7A14 , TPS7A53B Hi, I have a board I'm working on that requires the following power rails:
19V @ 2A
5V @ 3A
3V3 @ 1A
1V05 @ 1A
I'm trying to figure out whether I should be using 4 discrete regulators…
Hi Patrick,
What is generating the 3.3V rail? Also, what is the load requirements for the project or the expected load, is it only powering the DP83867IR?
This will help us provide a better suggestion for the LDO.
Perhaps looking into TPS7A14, TPS7A15…
Hey Chethana,
I see our new TPS7A14 https://www.ti.com/product/TPS7A14 as the best option here. It is 1A output current, with very low noise, and Vdo of 70mV if Vin-Vout>100mV.
Some other options are:
TPS7A11 -lower IQ, TLV755P -more package options, LP5…
HI Shyam,
I see here in your schematic that you are using the TPS7A14, not the TPS799, the TPS799 does not have a bias rail so I think I am looking at the correct part in the TPS7A14, correct me if I am wrong,
12V rail for the Bias is too high for this…
Part Number: TPS7A20 Other Parts Discussed in Thread: TPS7A94 , TPS7A21 , TPS7A57 Thank you for your help.
I am currently thinking of using TPS7A2033PDQNR to generate 3.3V.
The recommended capacitance range in the specifications is 1uF-200uF, but we are…
