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 0.1F, 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 selfprotection 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.
