These devices were designed using the latest computer techniques for optimizing the packaged IC thermal/electrical performance. The LM79LXXAC series, when combined with a minimum output capacitor of 0.1μF, exhibits an excellent transient response, a maximum line regulation of 0.07% VO/V, and a maximum load regulation of 0.01% VO/mA. 1 2 • • • • • • • Preset Output Voltage Error is Less than ±5% Over Load, Line and Temperature Specified at an Output Current of 100mA Easily Compensated with a Small 0.1μF 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 (SNVA009) for DSBGA Considerations The 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 package, the 8-lead SOIC package, and the 6-Bump DSBGA package. For output voltages other than the pre-set -5V, -12V and -15V, the LM137L series provides an adjustable output voltage range from -1.2V to -47V. Typical Applications *Required if the regulator is located far from the power supply filter. A 1μF aluminum electrolytic may be substituted. **Required for stability. A 1μF aluminum electrolytic may be substituted. Figure 1. Fixed Output Regulator −V0 = −5V − (5V/R1 + IQ) • R2, 5V/R1 > 3 IQ Figure 2.
