2nd BiB reg +3.3V installed in BII instead Trident again a big upgrade, for 1.2V I need to do a P2P V1.2R, about BII AVCC module I see 4 pins instead 3 pins (IN-GND-OUT) of Tridents any idea about the use of the 4th pin or I have only to use two pins like the Tridents?

Skylab, did you read the manual , from a link off post #1?

The minikits are a start, but additional caps are needed, current set resistors, and pot.
It also gives an idea which parts you want to go with based on build and voltage.

Yes, just did and it looks a bit complicated.

It is a bit complicated indeed. Because it covers a wide spread of applications and configurations. And it has a CCS and Vref to set. But give it a try to set a couple and then all becomes very easy to grasp. When you got the actual PCB and try for real, everything falls in place. In case of real sticking, tell us the application and current consumption so we give you the configuration, but try first, its rewarding. That's DIY. Assisted but not automatic. Automatic is no fun.

I have several questions:

-For 9V Vout wich Vref because in BiB manual only cover 5 Vout or 10-25 Vout? I think it's the same like the 10-25 Vout?

-When 5-5.5 Vout wich is the best reg BJT or IRF or depends of application: clocks, DACs, analog, etc.?

For 9V you can use one red LED, 5k trimmer.

Depends on the application. The specific BJT configuration gives less open loop gain extension, so I would use it on digital chips mainly. Also if someone tests the BJT for higher voltages, must look at its SOA before.

Has been done with a relative board before. Look at posts #20 to #29.

You would need a stronger (and slower than 9610) CCS Mosfet for the BiB. Try the 9530 there too. 9520 can do also and its faster, but more Vgs happy, comfortably set with 4 LEDS.

So, is it better a BJT configuration than a mosfet one, for a Buffalo Dac? (5.3V-575mA)
