A LM7805 7805 IC 5V Voltage Regulator IC is a voltage regulator that outputs 5 volts. An easy way to remember the voltage output by a LM78XX series of voltage regulators is the last two digits of the number. A LM7805 ends with “05”; thus, it outputs 5 volts. The “78” part is just the convention that the chip makers use to denote the series of regulators that output positive voltage. The other series of regulators, the LM79XX, is the series that outputs negative voltage. So: LM78XX: Voltage regulators that output positive voltage, “XX”=voltage output. Pin Details:- The LM7805, like most other regulators, is a three-pin IC. Pin 1 (Input Pin): The Input pin is the pin that accepts the incoming DC voltage, which the voltage regulator will eventually regulate down to 5 volts. Pin 2 (Ground): Ground pin establishes the ground for the regulator. Pin 3 (Output Pin): The Output pin is the regulated 5 volts DC. Features: LM7805 is a positive voltage regulator that outputs 5 volts The LM7805 is a three-pin IC Output Current up to 1.5A Thermal Overload Protection Short Circuit Protection Available in TO-220 package Thermal Resistance Junction-Cases (TO-220) : °C/W Thermal Resistance Junction-Air (TO-220): °C/W Operating Temperature Range: -40° – 125° C Package include: 1 x LM7805 7805 IC 5V Voltage Regulator IC
