The L7809 voltage regulator provides 9V Positive voltage as output and can provide local on-card regulation, eliminating the distribution problems associated with single-point regulation. Although designed primarily as a fixed voltage regulator, but it can be used with external components to obtain adjustable voltage.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"font-weight: 500;\"\u003e\u003cspan style=\"font-size: 28px;\"\u003e\u003cb\u003e\u003cstrong\u003eLM7809 Pinout Configuration\u003c\/strong\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003ctable style=\"font-weight: 400;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan style=\"font-size: 28px;\"\u003e\u003cb\u003e\u003cstrong\u003ePin Number\u003c\/strong\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"font-size: 28px;\"\u003e\u003cb\u003e\u003cstrong\u003ePin Name\u003c\/strong\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"font-size: 28px;\"\u003e\u003cb\u003e\u003cstrong\u003eDescription\u003c\/strong\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan style=\"font-size: 28px;\"\u003e1\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"font-size: 28px;\"\u003eInput (V+)\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"font-size: 28px;\"\u003eUnregulated Input Voltage\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan style=\"font-size: 28px;\"\u003e2\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"font-size: 28px;\"\u003eGround\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"font-size: 28px;\"\u003eConnected to Ground\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan style=\"font-size: 28px;\"\u003e3\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"font-size: 28px;\"\u003eOutput (Vo)\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan style=\"font-size: 28px;\"\u003eOutputs Regulated +9V\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3 style=\"font-weight: 500;\"\u003e\u003cspan style=\"font-size: 28px;\"\u003e\u003cb\u003e\u003cstrong\u003eLM7809 \/ 7809 Voltage Regulator Features:\u003c\/strong\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul style=\"font-weight: 400;\"\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 28px;\"\u003e9V Positive Voltage Regulator\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 28px;\"\u003eMinimum Input Voltage is 11V\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 28px;\"\u003eMaximum Input Voltage is 35V\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 28px;\"\u003eOutput Current: 1.5 A\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 28px;\"\u003ePSRR \/ Ripple Rejection: 55 dB\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 28px;\"\u003eOutput Type: Fixed\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 28px;\"\u003eInternal Thermal Overload and Short circuit current limiting protection is available.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 28px;\"\u003eJunction Temperature maximum of 125 degree Celsius\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 28px;\"\u003eAvailable in TO-220, TO-3 and KTE package\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"font-weight: 400;\"\u003e\u003cspan style=\"font-size: 28px;\"\u003e\u003cb\u003e\u003cstrong\u003e \u003c\/strong\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\"\u003e\u003cspan style=\"font-size: 28px;\"\u003e\u003cb\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003c\/b\u003e Complete Technical Details can be found in the \u003cb\u003e\u003cstrong\u003e7809 datasheet\u003c\/strong\u003e\u003c\/b\u003e given at the end of this page.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"font-weight: 500;\"\u003e\u003cspan style=\"font-size: 28px;\"\u003e\u003cb\u003e\u003cstrong\u003eL7809 Voltage Regulator Equivalent\u003c\/strong\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp style=\"font-weight: 400;\"\u003e\u003cspan style=\"font-size: 28px;\"\u003eLM7806, LM7824, LM7815, LM7812, LM317, LM7905, LM7912.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 style=\"font-weight: 500;\"\u003e\u003cspan style=\"font-size: 28px;\"\u003e\u003cb\u003e\u003cstrong\u003eBrief Description of 7809 Voltage Regulator IC\u003c\/strong\u003e\u003c\/b\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp style=\"font-weight: 400;\"\u003e\u003cspan style=\"font-size: 28px;\"\u003eVoltage regulators are very common in electronic circuits.
