LM320L/LM79LXXAC Series
3-Terminal Negative Regulators
General Description
The LM320L/LM79LXXAC dual marked series of 3-terminal
negative voltage regulators features fixed output voltages of
5V, 12V, and 15V with output current capabilities in
excess of 100mA. These devices were designed using the
latest computer techniques for optimizing the packaged IC
thermal/electrical performance. The LM79LXXAC series,
even when combined with a minimum output compensation
capacitor of 0.1μF, exhibits an excellent transient response,
a maximum line regulation of 0.07% V
O
/V, and a maximum
load regulation of 0.01% V
O
/mA.
The LM320L/LM79LXXAC series also includes, as self-
protection circuitry: safe operating area circuitry for output
transistor power dissipation limiting, a temperature indepen-
dent short circuit current limit for peak output current limiting,
and a thermal shutdown circuit to prevent excessive junction
temperature. Although designed primarily as fixed voltage
regulators, these devices may be combined with simple
external circuitry for boosted and/or adjustable voltages and
currents. The LM79LXXAC series is available in the 3-lead
TO-92 package, 8-lead SOIC package, and the 6-Bump
micro SMD package. The LM320L series is available in the
3-lead TO-92 package.
For output voltage other than 5V, 12V and 15V, the
LM137L series provides an output voltage range from 1.2V
to 47V.
