General Description
The TS79M00 series of fixed output negative voltage regulators are intended as complements to the popular
TS78M00 series device. These negative regulators are available in the same seven-voltage options as the TS7900
devices. In addition, one extra voltage option commonly employed in MECL systems is also available in the negative
TS79M00 Series. Available in fixed output voltage options from -5.0 to -24 volts, these regulators employ current
limiting, thermal shutdown, and safe-area compensation--making them remarkably rugged under most operating
conditions. With adequate heat sinking they can deliver output currents in excess of 0.5 ampere.

Output Voltage: -5 & -12V
Output current up to 0.5A
No external components required
Internal thermal overload protection
Internal short-circuit current limiting
Output transistor safe-area compensation
Output voltage offered in 4% tolerance
A common ground is required between the input and the
output voltages. The input voltage must remain typically
2.0V above the output voltage even during the low point on
the Input ripple voltage.

distance from power supply filter.
** = Co is not needed for stability; however, it does improve
transient response.
