| Market Reality | The 79xx series is the negative rail of every split supply that ever fed an op-amp, an audio stage or an instrument: -5V, -8V, -9V, -12V, -15V, -18V and -24V fixed 1.5A regulators in the same TO-220 body as the 78xx - and with a mirrored pinout that catches one swap per bench per year. The digits choose the voltage, the suffix grade (AC = 2 percent tolerance) chooses precision, and the prefixes (L, MC, KA, LM) are the familiar second-source names. The classic failure this page exists for: treating a 7905 as a misplaced 7805, when it differs in polarity, pin order AND tab potential - three separate ways to smoke a board at once. | The 79xx series is the negative rail of every split supply that ever fed an op-amp, an audio stage or an instrument: -5V, -8V, -9V, -12V, -15V, -18V and -24V fixed 1.5A regulators in the same TO-220 body as the 78xx - and with a mirrored pinout that catches one swap per bench per year.
