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.
Features
Standard Application Circuit
●
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.
XX = these two digits of the type number indicate voltage.
* = Cin is required if regulator is located an appreciable
distance from power supply filter.
** = Co is not needed for stability; however, it does improve
transient response.

 Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as
possible, and thermal effects must be taken into account separately.
 This specification applies only for DC power dissipation permitted by absolute maximum ratings.
