Description
The GM7800 series are classic regulators, which are use-
ful in a wide range of applications. For example, you can
use them for local on-card regulation to eliminate the distri-
bution and problems associated with single point regula-
tion.
Features
Output current up to 1.5A
Output Voltages 5V, 6V, 8V, 8.5V, 9V, 10V,
12V, 15V, 18V, 20V, 24V and 27V
3- Terminal Regulators
Internal Thermal Overload Protection
Internal Short-Circuit Current Limiting
Output Transistor Safe-Area Protection
TO-220, TO-252 and TO-263 Packages
High Power Dissipation Capability
Direct replacements for LM78xx
The wide range of output voltages (5V to 27V) make them
useful in an endless list of applications. Although designed
as fixed voltage regulators, you can add a few external
components to make adjustable voltages and currents.
Current limiting prevents the peak output current to a safe
value. Safe-area protection of the output transistor limits in-
ternal power dissipation. If internal power dissipation be-
comes too high for the heat sinking provided, the thermal
shutdown circuit activates to prevent the regulator from
overheating. These versatile workhorses are easy to use.
You do not need to bypass the output, although this does
improve transient response. Input bypass is needed only if
you place the regulator far from the filter capacitor of the
power supply.
Application
Post-Regulator Switching DC/DC
Converters
Bias Supply for Analog Circuits
Instrumentation and Audio Systems
Logic Systems
Others too numerous to mention
The GM7800 series is available in TO-220, TO-252 and
TO-263 packages.

For a positive regulator, a 0.33µF bypass capacitor should be used on the input terminals.
While not necessary for stability, an output capacitor of 0.1µF may be used to improve the
transient response of the regulator. These capacitors should be on or as near as possible
to the regulator terminals .
