Series 3-Terminal Negative Regulators

The LM320L,LM79LXXAC dual marked series of 3-terminal negative voltage Regulators LM79L12 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 0.1?F, exhibits an excellent transient response, a maximum line regulation of 0.07% VO/V, and a maximum load regulation of 0.01% VO/mA.
The LM320L/LM79LXXAC series also includes, as self-protection circuitry: safe operating area circuitry for output Transistor power dissipation limiting, a temperature independent 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.
