Voltage Regulator Ic 723 Can Supply Load Current Up To. Current limit is about i v r 0 6 r10. It is basically used in the series regulator application.
When the load voltage across r10 exceeds about 0 6v it turns on q2 which clamps q1 vbe to reduce voltage. When there is quite a distance in cms from the ic to the filter capacitor of the unregulated power supply there may occur unwanted oscillations within the ic due to lead inductances within the circuit. In other words an ideal regulator would produce a voltage that is for example exactly 3 3 v when connected to a 100 kω load and exactly 3 3 v when connected to a 5 ω load.
Within the common application the ic 723 voltage regulator circuit offers an output of 2 37 volts however in numerous situations it becomes essential to be able to go have voltages as low as 0 v.
The device can be set to work as both posistive and negaive voltage regulators with an output voltage ranging from 2 v to 37 v and output current levels upto 150 m a. In our circuit this is made available from an lm337 negative regulator lm337. The device can be set to work as both positive and negative voltage regulators with an output voltage ranging from 2 v to 37 v and output current levels up to 150 m a. The datasheet s 723 supply with external pass transistor and current limit.
