LM320L/LM79LXXAC

      The LM320L/LM79LXXAC has features including Preset output voltage error is less than ±5% overload,line and temperature;Specified at an output current of 100mA;Easily compensated with a small 0.1F output capacitor;Internal short-circuit, thermal and safe operating area protection;Easily adjustable to higher output voltages;Maximum line regulation less than 0.07% VOUT/V;Maximum load regulation less than 0.01% VOUT/mA;See AN-1112 for micro SMD considerations.
      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.
