GI78MXX
3-TERMINAL POSITIVE VOLTAGE REGULATOR
Description
The GI78MXX 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. GI78MXX is characterized for operation from 0 to +125 .
