Overview

LM79XX 3-Terminal Negative voltage Regulators DESCRIPTION These voltage regulators are designed as fixed negative voltage regulators for a wide variety of applications including local, on-card regulation.
Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.
FEATURES ■ Output current in excess of 1.
0A ■ No external components required ■ Output Voltages (-5V, -6V, -8V, -9V, -10V, -12V, -15V, -18V) ■ Internal Thermal shutdown and SOA protection ■ Output voltage offered in 4% Tolerance ■ Pb-Free Packages are available ■ High ESD Level (HBM>8000V, MM>800V) TYPICAL APPLICATION The input voltage must remain typically 2.
0V above the output voltage even during the low point on the ripple voltage.
* CI is required if regulator is located an appreciable Distance from power filter.
* CO improves transient response.
Values of ≤ 1.
0 µF could cause instability.

Maximum ratings are stress ratings.
Functional operation above the recommended operating conditions is not implied.
Extended exposure to stresses the above the recommended operating conditions may affect device reliability.
PD(max) = (TJ(max)–TA) ÷ θJA.
Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
