Voltage Regulator L7824

• L7824 is a fixed-voltage integrated-circuit voltage regulator designed for a wide range of applications. The L7824 voltage regulator provides 24V Positive voltage as output to provide a convenient power source for most TTL components. Although designed primarily as a fixed voltage regulator, but it can be used with external components to obtain adjustable voltage.
• Voltage regulators are very common in electronic circuits. They provide a constant output voltage for a varied input voltage. The name 7824 signifies two meanings, “78” means that it is a positive voltage regulator and “24” means that it provides 24V as output. So our 7824 will provide a +24V output voltage.
• The output current of this IC can go up to 1.5A. But the IC suffers from heavy heat loss hence a Heat Sink is recommended for projects that consume more current. For example, if the input voltage is 35V and you are consuming 1A, then (35-5) * 1 = 30W. This 30 Watts will be dissipated as heat.
