Diagram Of Voltage Regulator. The circuits used for voltage stabilizers are different. Electronic voltage regulators have been used on many cars since the mid 1970s.
Fixed negative voltage regulator circuit diagram. This lm317 circuit is capable to provide variable dc power supply with an. Number of popular voltage regulator ic units.
The output voltage is then fedback to a sampling circuit and then compared with a reference voltage and sent back to the output.
Lm117 is a reliable ic which can output regulated voltage in the range of 12 volts to 37 volts. The capacitors act as line filtration. The 7900 series are negative voltage regulators. A typical 7800 series voltage regulator is used for positive voltages.
