Description
I GO
I GO
The LM78MXXJ3 series of three-terminal positive regulators are
available in the TO-252 package and with 5V, 6V, 8V, 9V, 12V, 15V,
18V and 24V fixed output voltages, making them useful in a wide range of applications. These
regulators can provide local on-card regulation, eliminating the distribution problems associated with
single point regulation. Each type employs internal current-limiting ,thermal shut-down and safe operating
area protection, making them essentially indestructible. If adequate heat sinking is provided, they can
deliver over 500mA output current. Although designed primarily as fixed voltage regulators, these devices can
be used with external components to obtain adjustable voltages and currents.
