GM78L09

PRELIMINARY GM78L00 100 mA POSITIVE VOLTAGE REGULATORS Wide range of Fixed Output Voltages Output Current up to 100 mA No External Components Required Internal Thermal Overload Protection Internal Short Circuit Current-Limiting Available in TO-92, SOT-89 and SOP-8 packages The GM78L00 series of positive voltage regulators are low-cost devices providing a simple solution for a wide variety of applications requiring a regulated supply of up to 100mA. These virtually indestructible positive voltage regulators are protected by thermal shutdown and internal current-limiting. Most applications require no external components. The GM78L00’s are very versatile. Use them as fixed voltage regulators in a wide range of applications, including local on-card regulation for elimination of noise and distribution problems associated with single-point regulation. They can also be used with power pass elements to make high current voltage regulators. The GM78L00’s offer impressive performance advantages over oldfashioned zener diode-resistor combinations, providing lower output impedance and reduced quiescent current, along with lower noise. www.DataSheet4U.com PIN CONFIGURATIONS TO-92 (TOP VIEW) 3 1 2 3 INPUT GROUND OUTPUT SOT-89 (Top View) 1 2 3 VOUT GND VIN SOP-8 (TOP VIEW) V OUT GND GND NC 1 2 3 4 8 7 6 5 V IN GND GND NC REPRESENTATIVE BLOCK DIAGRAM INPUT Q3 15k Q10 Q1 5.0k Q5 Q11 Q12 3.0k OUTPUT 3.8k Q4 Q6 2.2k 1.9k Z1 420 Q2 Q7 1.0k GROUND C Q8 Q9 2.85k 0-25k 1.2k Revisio...
