The LM79XX series of 3-terminal regulators is available with fixed output voltages of −5V, −12V, and −15V. These devices need only one external component—a compensation capacitor at the output. The LM79XX series is packaged in the TO-220 power package and is capable of supplying 1.5A of output current. These regulators employ internal current limiting safe area protection and thermal shutdown for protection against virtually all overload conditions.
“Dual regulated power supply is needed in many digital and analog circuits.Operational Amplifier like UA741 needed dual regulated power supply to operate.In normal regulated power supply,only positive voltage is regulated this leads to ground loop coupling which …
