Description
OGI
The LM78MXXM3 series of three-terminal positive regulators are available in the SOT-89 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.
