Pb Free Plating Product CORPORATION GSC79LXX ISSUED DATE :2006/06/26 REVISED DATE : NEGATIVE VOLTAGE REGULATOR Description The GSC79LXX series of fixed-voltage monolithic integrated circuit voltage regulators are 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. Features Fixed output voltage of -5V, -6V, -8V,-9V, -12V, -15V, -18V, -24V Internal Short-Circuit Current Limiting Internal Thermal Overload Protection No External Components Required Package Dimensions REF.
