MC79M00/D
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.
Features
• 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

A common ground is required between the input
and the output voltages. The input voltage must
remain typically 1.1 V more negative even during
the high point of the input ripple voltage.
