Hello, is it safe to leave unused output (for example VR2) of HMC1060 floating? Or should I keep the capacitor between VR2 and RD2 (for stability)?
Thank you,
Anh

Is it possible to get more current from a single output by combining outputs.
For example, I need 450 ma at 5V. Can I somehow combine VR4 and VR1 to get the combined current output?
Hi,
I will be adding these parts to the ADIsimPower Linear Regulator design tool, I have some questions about these parts:
HMC860:
Can I short RDx to VRx to get 1.2V output? The datasheet says Vout 2.5V to 5.2V, is this because it's been tested only…
Hi Michael,
The part is characterized with separate supplies and I don't have data taken with shared supplies. We are using HMC1060 ( single chip having 4 LDOs) on the evaluation board and isolation is poorer comparing separate LDO case. We did not see…
One regulator for the 3.3V supply is sufficient. It was believed that a separate supply could reduce spurious, but it has little discernable effect.
The HMC1060 is a regulator which can generate both the 5V and 3.3V rails.

Thanks you for your reply. I have resolve the question. The voltage of HMC1060 output unstablly. The tantalum capacitor of hmc1060 output circuits is too far to output unwanted voltages.
Thanks again.
Hi,
You didn't mention your application or the loop BW you're using so the following is assuming that REF / PFD, Icp etc. must remain as they are.
1) I don't recommend attempting to use the HMC767 for an 8.0 GHz application. Over process & temperature…
Good morning everyone,
In the HMC830 schematic there is a net named REG_EN(AD4). I have supposed that the net needs to bring a enable signal for the HMC1060 regulator.
We are realizing a breadboard where the 3.3V and 5V power supplies are provided by…
I'm thinking of using HMC702 and HMC1060 to build a phase lock loop.HMC702 is a quite great frequency synthesizer IC and HMC1060 is a LDO which can produce one 5V 300mA,two 3.3V 50mA and one 3.3V 100mA in one IC.In HMC702's datasheet ,it says that +3…
