500 mA Negative Voltage
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
DEVICE TYPE/NOMINAL OUTPUT VOLTAGE
Nominal Output Voltage
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.
XX These two digits of the type number indicate
* Cin is required if regulator is located an
appreciable distance from power supply filter.
** CO improve stability and transient response.
