CA3130 PDF

Figures 6A and 6B show the CA connected for both dual-and single-supply operation. Dual-supply Operation: When the output voltage at Terminal 6 is 0V, the currents supplied by the two power supplies are equal. When the gate terminals of Q8 and Q12 are driven increasingly positive with respect to ground, current flow through Q12 from the negative supply to the load is increased and current flow through Q8 from the positive supply decreases correspondingly. When the gate terminals of Q8 and Q12 are driven increasingly negative with respect to ground, current flow through Q8 is increased and current flow through Q12 is decreased accordingly. Single-supply Operation: Initially, let it be assumed that the value of RL is very high or disconnected , and that the input- terminal bias Terminals 2 and 3 is such that the output terminal No.

This circuit has a special feature that can supply output voltage widely range is during 0. With a value of the load regulation changes not more than 0. The working of circuit The Simple adjustable voltage and current Power supply circuit diagram The stability of load regulation when changing the input voltage about of 0.

The noise output signal is less than uV. This circuit can provide an output voltage in a wide range using IC-CA op-amp. Which we set the input voltage range of about 0V. The rate of the output voltage can not by adding Q4 between this IC and transistor both series. This circuit has a high threshold, makes the regulation is accurately high level.

Q3 is the limited current output. When the VR1 fully anticlockwise, Q3 current limit around 0. This current limit, it will not work When the VR2 rotate clockwise until it stops. The regulator circuit works as follows, is IC-CA compares the voltage of the output are fed into the positive input pin of the IC. There is Reference voltage entered to negative input pin, output voltage of regulator is to be lowered by the voltage dividing circuit to prevent damage to the IC.

Reference voltage can be adjusted by VR2, which should be a good quality. If the axis of VR2 is close to the signal output is not constant. Another IC, is CA functions compensate, the reference voltage from changing the temperature. This IC consists of transistors 4 pcs 2N, 2N and 2N , which can be used as a diode or zener diode and a transistor, which acts to reduce the output impedance of the reference voltage generator circuit.

In addition, the voltage reference IC can also be reduced to the CA This circuit will fully dependent the help the IC between these two. If IC1 is not working properly, it can cause damage IC2, transistors all, should stand at least 55V voltage so as not to damage it. You can look other power supply circuits: Click Here.
