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: Is this a positive or negative regulator?\u003cbr\u003eA: Negative.
