space DESCRIPTION
The LM79XX series of 3-terminal regulators is
available with fixed output voltages of -5V, -12V, and
-15V. These devices need only one external
component—a compensation capacitor at the output.
The LM79XX series is packaged in the TO-220 power
package and is capable of supplying 1.5A of output
current. Connection Diagram Figure 1. TO-220 Package

See Package Number NDE0003B Typical Applications These regulators employ internal current limiting safe
area protection and thermal shutdown for protection
against virtually all overload conditions.
Low ground pin current of the LM79XX series allows
output voltage to be easily boosted above the preset
value with a resistor divider. The low quiescent
current drain of these devices with a specified …
