Texas Instruments MC79L05A
This series of fixed negative-voltage integrated-circuit voltage regulators is designed OUTPUT for a wide range of applications. These include INPUT on-card regulation for elimination of noise and COMMON distribution problems associated with single-point regulation.MC79L00 SERIES NEGATIVEĆVOLTAGE REGULATORS D 3-Terminal Regulators D Output Current Up To 100 mA D No External Components Required D Internal Thermal-Overload Protection D Internal Short-Circuit Current Limiting D Direct Replacement for Industry-Standard MC79L00 Series D Available in 5% or 10% Selections SLVS011D − OCTOBER 1982 − REVISED AUGUST 2003 D PACKAGE (TOP VIEW) OUTPUT 1 INPUT† 2 INPUT† 3 NC 4 8 NC 7 INPUT† 6 INPUT† 5 COMMON † Internally connected NC − No internal connection description/ordering information LP PACKAGE (TOP VIEW) 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.
