hi. im trying to run the circuit the i attach.
first off all i cant find the component CA3086. so im trying to build it like in the data-sheet, but it not working.
can somone help me?

Hello,

Here is a PDF from intersil with the spice model.

PS I edited your post as you used an unwanted text.

 

Simply try to use a 15V zener diode and 6.8V Zener together with 2n2222 transistor .

how do i use it?

 

tnx i
how do i use it?

This Spice model will not work properly with your circuit. Because I do not seen any Bv parameter.

 

first off all i cant find the component CA3086. so im trying to build it like in the data-sheet, but it not working.
can somone help me?

Looking at that schematic and looking at the diagram of the CA3086, which transistor is conducting?

on edit ... showed the full CA3086 portion of that schematic

[sarcasm] It must be a working circuit, after all, it's on the internet.[/sarcasm]

Wrong ??

i also find this one that i think is good but i cant run it on the spice without any error

 

Can you show us your pspice diagram and error message?

 

Can you show us your pspice diagram and error message?

i took care of the capcitor eror. in the Amp3130 it showing me in the green eror "WARNING(ORNET-1119): No PSpiceTemplate for U1, ignoring"

 

The problem is that you should use the model from Orcad\Capture\library\PSpice not from Orcad\Capture\library\

Also Fix your connections at node where R12, R11 and R13 are connected. Also at R2 D5 C2 node.

 

The problem is that you should use the model from Orcad\Capture\library\PSpice not from Orcad\Capture\library\

so i copy the 3130 to pspice libary and it didnt change nothing )=

what is the problem with the component you wrote?

 

LOL, try use a different type of a opamp , for example TL071.

 

Hello,

Also the collector of Q1 is on the wrong side of R2 (2k2).

Bertus

 

LOL, try use a different type of a opamp , for example TL071.

so i tried the Tl071 and he is writing me the same error.

 

So i use Multisim and its work.

can somone explain me in simple word what is the job of CA3086 in the circuit? what is the job of the zener diode in this model?

also i will glad if somone can explain me what is the job of the capcitor that connect in leg 1 - 8 in CA3130 component ?

i found this article
http://www.eleccircuit.com/circuit-power-supply-regulator-01-50v-1a-by-ic-ca3130-ca3086-2n3055/
but my english is not that good

 

Well in simple word?
For this circuit
http://forum.allaboutcircuits.com/attachments/simulation-2-jpg.97359/
Q3 , Q4 and 4.3kΩ - a shunt voltage regulators to power the op amp (CA3130).
Q1,Q2,Q5 together with 2.2kΩ , 62kΩ, 1kΩ forms a reference voltage for a error amplifier (CA3130).
And this capacitor is a compensation capacitor to prevent oscillation.
