Hi Will,
LP5951 is close to same Iq and Iq shutdown performance, but dropout is higher.
LP3990 has higher Iq, but lower Iq shutdown and slightly higher typical dropout.
In addition to TPS7A05, these parts are the closest TI LDOs for this application…
Hi Mohammad,
We already have the model for LM337 and LP3990:

For the other two parts: TPS60402 and LM334, we will look into this inquiry.

I've selected LP3990-1.2.. Its data sheet calls for ESR of output capacitor 5 mOhm min, 500 mOhm max. At what frequency? For instance Kemet C0805C225K8RAC according to KEMET SPICE has 556 mOhm at 1kHz, 62.62 mOhm at 10 kHz, 13.5 mOhm at 100 kHz and absolute…
This is Charger application support. The charger BQ24133 should work in the block diagram Thanks!

Hi Imelda,
Thanks for reaching out with this question. What we would recommend here is that customers look at the impedance of their PoC network across the operating frequency range of the device. This would cover the forward channel and the back channel…
Hello Tsukui-san,
With FPGA's their actual power needs vary depending on the clock speed and other variables.
Therefore many times TI does not have a design for a specific FPGA.
One good way to build a design is to use Webench FPGA Architect.

Hello Martijn,
The DS90UB927-Q1 does not list Power over Cable, in the datasheet. The EVM does uses the STP data output. However the device is capable of Power over Coax. As you indicated the 50 ohm power over cable , while the STP is 100 ohm differential…
