Product specification
LM7824J
3-Terminal 1A Positive Voltage Regulator
GENERAL DESCRIPTION
The LM7824 series of three terminal positive regulators are available in the TO-220 package and with
several fixed output voltages, making them useful in a wide range of applications. Each type employs
internal current limiting, thermal shut down and safe operating area protection, making it essentially
indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although
designed primarily as fixed voltage regulators, these devices can be used with external components to
obtain adjustable voltages and currents.
