Does voltage regulator need to be grounded?
Reference is generated by grounded zener diode and output feedback voltage is derived from potential divider that is connected to output and ground. So the ground is absolutely necessary for voltage regulator to work.
What are the absolute values of virtual ground regulators?
When a “complimentary pair” of fixed value voltage regulators are used to create a virtual ground this way, the absolute values of their output voltages are each 1/2 of the rail-to-rail voltage.
Where do you find voltage regulators in audio?
The IC’s bowed before us. Voltage regulators are found in the power supply section of virtually any piece of audio gear. They are designed to deliver a constant, rock solid voltage to power the audio circuits from. Voltage regulators are typically small 3 legged chips (or IC’s), with an exposed metal tab.
How is the voltage of a voltage regulator adjusted?
The LM336BZ-2.5V voltage reference compensates for the LM317’s (+1.25V) internal reference and the LM337’s (-1.25V) internal reference. So when the LM317/LM337 adjust pins are connected inside the R1/R2 voltage divider as shown, each voltage regulator output voltage becomes 1/2 of whatever the rail-to-rail voltage happens to be.
What kind of chip is a voltage regulator?
Voltage regulators are typically small 3 legged chips (or IC’s), with an exposed metal tab. And like all IC’s, they suffer from the inability to put high quality or high value capacitors inside of them. But with discrete voltage regulators, one can do exactly that.
What kind of part is a voltage regulator?
The voltage regulator is a potted electronic component in a square cast aluminum chassis shaped like an open box, somewhat like a sardine can. The new part has some modifications. They have added a fuse and a ground wire that were lacking on the original part.
Which is better IC regulator or discrete voltage regulator?
But with discrete voltage regulators, one can do exactly that. Our discrete voltage regulators have at least 15 times lower output noise than IC regulators. They have 52dB (about 300X) better rejection of any noise coming into them, and 4X better load regulation than any other 3 terminal IC regulator that one can find to compare them against.
