It can then be repaced with a fixed resistor having a preferred value closest to the measured value.
#Variable resistor in multisim full
It will quite a bit of heat while working full load current.įor this reason, this circuit is not recommended for use in handheld throttles.
But we need to use a substantial heatsink for IC1- LM350. This circuit is a low output voltage but high current. So we use both diodes to protect any current that is damage to the regulator. Only logged in customers who have purchased this product may leave a review. Since the high reverse currents usually flow to the regulator when the devices power down. 10k ohm Trimpot RM065 Package is a type of variable resistor, It can be easily mounted on PCB and adjusted using screw driver. In the circuit, we use diodes D1 and D2 as the feedback blocker. We need to use Both diodes that have a current rating of at least 3 amp. They can happen if this type of circuit is variable high voltage power supply, and without the protection of D3 and D4. Such as the output voltage is higher than the input voltage to the regulator. Thus, the output voltage of 0 voltsĪnother advantage of both diodes(D3, D4), will prevent damage to the regulator during certain adverse conditions. Multisim will place the wire between the components selected.
After Mounting the required components wire them up. Place the Transistor on the Circuit and double click to place it. With diodes, D3 and D4 will provide a voltage drop of approximately 1.4 volts. Open Multisim Place the Resistor on the Circuit and double click to place it.
It will make an output voltage lower than the input of 0.7V. Look: Basic circuit of LM350 LM350 Basic circuit See LM350 Datasheet! Because these regulators (LM317, LM350, LM338) has a minimum output voltage of 1.25 volts. We determine the voltage at the output of the regulator, with values of R1 and R2.
