ON MC79M12 500 ma negative voltage regulator Datasheet

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.

STANDARD APPLICATION
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.
XX These two digits of the type number indicate
nominal voltage.
* Cin is required if regulator is located an
appreciable distance from power supply filter.
** CO improve stability and transient response.

Protection Diodes
Diode D2 prevents output capacitor from discharging thru
the MC79M15 during an input short circuit or fast switch off
of power supply.
When external capacitors are used with MC79M00 series
regulator it is sometimes necessary to add protection diodes
to prevent the capacitors from discharging through low
current points into the regulator or from output polarity
reversals. Generally, no protection diode is required for
values of output capacitance less then 10mF. Figure 2 shows
the MC79M15 with the recommended protection diodes.
• Opposite Polarity Protection
Diode D1 protects the regulator from output polarity
reversals during startup, power off and short-circuit
operation.
• Reverse-bias Protection
