3-TERMINAL 0.1A NEGATIVE VOLTAGE REGULATOR LM79LXX FEATURES z z z z z z TO-92 PKG Output Current Up to 100mA No External Components Internal Thermal Overload Protection Internal Short-Circuit Limiting Output Voltage of 5V, 6V, 8V, 9V, 12V, 15V, 18V and 24V Moisture Sensitivity Level 3 DESCRIPTION SOT-89 PKG This series of fixed-voltage monolithic integrated-circuit voltage regulators is designed for a wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used with power-pass elements to make high current voltage regulators. Each of these regulators can deliver up to 100mA of output current. The internal limiting and thermal shutdown features of these regulators make them essentially immune to overload. When used as a replacement for a zener diode-resistor combination, an effective improvement in output impedance can be obtained together with lower-bias current.

Note 2. LM79LXX Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible. Thermal effects must be taken into account separately. All characteristics are measured with a 0.33uF capacitor across the input and a 0.1uF capacitor across the output. This specification applies only for DC power dissipation permitted by absolute maximum ratings.
