It\u2019s actually not a coincidence, but a way for people to easily remember the voltage outputs. The LM7805 is part of the LM78XX series of voltage regulators, where the XX indicates the voltage that each regulator outputs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What you need to know when using the LM7805<\/strong><\/h3>\n\n\n\n<p style=\"color:#000000\" class=\"has-text-color\"><strong>Absolute Maximum Input Voltage<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>35V<\/li><\/ul>\n\n\n\n<p style=\"color:#000000\" class=\"has-text-color\"><strong>Recommended Operating Conditions<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Input Voltage: Minimum 7V, Maximum 25V<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>Output Current: 1.5A<\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>Operating Virtual Junction Temperature: Minimum 0, Maximum 125\u00b0C<\/li><\/ul>\n\n\n\n<p style=\"color:#000000\" class=\"has-text-color\"><strong>Possible High Temperatures<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>If differences between the input and output voltages are not well managed, LM7805 can overheat, which may result in malfunctioning.
