3-TERMINAL POSITIVE VOLTAGE REGULATOR

GJ78MXX

Description

The GJ78MXX 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 it 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 it essentially indestructible. If adequate heat sinking is provided, they can deliver over 0.5A

output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain

adjustable voltages and currents. GJ78MXX is characterized for operation from 0к to +125к.
