MC79M00 Series

500 mA Negative Voltage Regulators

The MC79M00 series of fixed output negative voltage regulators are intended as complements to the popular MC78M00 series devices. Available in fixed output voltage options of ?5.0 V, ?8.0 V, ?12 V and ?15 V, these regulators employ current limiting, thermal shutdown, and safe?area compensation, making them remarkably rugged under most operating conditions. With adequate heatsinking they can deliver output currents in excess of 0.5 A.

?No External Components Required

?Internal Thermal Overload Protection

?Internal Short Circuit Current Limiting

?Output Transistor Safe?Area Compensation

?Also Available in Surface Mount DPAK (DT) Package

?Pb?Free Packages are Available
