HMC860 line regulatiuon


I used the HMC860 with VCC=3.4V and all my outputs are 2.8V.

the load is 10-20 mA each.

I changed the VCC by 0.1V and get ~1mV on the output.

Is it normal?

I expected much higher line regulation.

Please advice.

Is there any other part with similar performance (low noise, at least 2 LDO in 1 package) that will give better results?
