GM7900 Series
1.5A NEGATIVE VOLTAGE REGULATOR
Description
Features
Output current up to 1.5A
The GM7900 series of fixed-negative voltage
monolithic integrated circuit voltage regulators is
designed to complement Series GM7800 in a
wide range of applications.
Available Output Voltage Options from -
5Vto -24V
3- Terminal Regulators
These applications include on-card regulation for
elimination of noise and distribution problems
associated with single-point regulation. Each of
these regulators can deliver up to 1.5A of output
current.
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
The internal limiting and thermal shutdown
features of these regulators make them
essentially immune to overload. In addition to use
as fixed-voltage regulators, these devices can be
used with external components to obtain
adjustable output voltages and current and also
as the power pass element in precision
regulators.
The GM7900 series are available in TO-220, TO-
252, TO-263 packages.

When using a negative regulator, bypass capacitors are a must on both input and output. Recommended values are 2µF on the
input and 1µF on the output. It is considered good practice to include a 0.1µF capacitor on the output to improve the transient
response. These capacitors may mylar, ceramic, or tantalum, provided that they have good high frequency characteristics
