3-pin, 100mA, Fixed Negative Voltage Regulator - MC79L


This series of fixed negative-voltage integrated-circuit voltage regulators is designed for a wide range of applications. These include 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.


  • 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
