Each is marked with the Signetics logo, \"KOREA,\" \"5G,\" and \"MC7915C.\" Never installed, with clean, unsoldered leads. Light handling marks on tabs and leads, as pictured.\u003cbr\u003eThe MC7915C is the -15V member of the MC7900 negative regulator series. It is commonly paired with a 7815 to build a ±15V split supply for op-amp, audio and test-equipment circuits. Specifications below come from the MC7900-series datasheet.\u003cbr\u003e\u003cbr\u003eFeatures:\u003cbr\u003eFixed -15V negative output\u003cbr\u003e1A output current with adequate heatsinking\u003cbr\u003e-35V maximum input voltage\u003cbr\u003e1.3V typical dropout\u003cbr\u003e60dB typical ripple rejection\u003cbr\u003eInternal thermal overload protection\u003cbr\u003eInternal short-circuit current limiting\u003cbr\u003eOutput transistor safe-area compensation\u003cbr\u003eTO-220 package for heatsink mounting\u003cbr\u003eOriginal Signetics manufacture, Korea\u003cbr\u003e10 pieces\u003cbr\u003e\u003cbr\u003eCompatibility:\u003cbr\u003eDirect replacement for MC7915C and other 7915 -15V 1A negative regulators in TO-220, including MC7915CT, LM7915, KA7915, L7915CV and UA7915. On the 79xx series the pinout differs from the positive 78xx series. Pin 1 is Ground, Pin 2 is Input and Pin 3 is Output, and the metal tab connects to the Input, not to ground. Use an insulator kit if the heatsink is grounded.\u003cbr\u003e\u003cbr\u003eQ\u0026amp;A\u003cbr\u003eQ: What is the pinout of the MC7915C?\u003cbr\u003eA: Pin 1 Ground, Pin 2 Input, Pin 3 Output. The tab is connected to the Input (Pin 2).\u003cbr\u003eQ: Can I mount the tab directly to a grounded heatsink?\u003cbr\u003eA: No. The tab carries the negative input voltage, so use a mica or silicone insulator and a shoulder washer.\u003cbr\u003eQ: What replaces an MC7915C?\u003cbr\u003eA: Any 7915 -15V 1A TO-220 regulator, such as onsemi MC7915CTG, LM7915, KA7915 or ST L7915CV.\u003cbr\u003eQ: What input voltage does it need?\u003cbr\u003eA: The input must be at least about 2V more negative than -15V (around -17V or lower), with a -35V maximum.\u003cbr\u003eQ: How many are included?\u003cbr\u003eA: Ten.\u003cbr\u003e\u003cbr\u003eDISCLAIMER\u003cbr\u003eItems are new old stock, sold as pictured.
