MC79L00 SERIES NEGATIVE-VOLTAGE REGULATORS SLVS011D – OCTOBER 1982 – REVISED AUGUST 2003 D D D D D D D 3-Terminal Regulators Output Current Up To 100 mA No External Components Required Internal Thermal-Overload Protection Internal Short-Circuit Current Limiting Direct Replacement for Industry-Standard MC79L00 Series Available in 5% or 10% Selections D PACKAGE (TOP VIEW) OUTPUT INPUT† INPUT† NC 1 8 2 7 3 6 4 5 NC INPUT† INPUT† COMMON † Internally connected NC – No internal connection description/ordering information LP PACKAGE (TOP VIEW) This series of fixed negative-voltage OUTPUT integrated-circuit voltage regulators is designed INPUT for a wide range of applications. These include COMMON on-card regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used to control series pass elements to make high-current voltage-regulator circuits. One of these regulators can deliver up to 100 mA of output current. The internal current-limiting and thermal-shutdown features essentially make the regulators immune to overload. When used as a replacement for a Zener-diode and resistor combination, these devices can provide an effective improvement in output impedance of two orders of magnitude, with lower bias current.
