TS79M00 series
3-Terminal Medium Current Negative Voltage Regulator
Pin assignment:
1. Ground
2. Input
3. Output
(Heatsink surface
connected to Pin 2)
Voltage Range - 5V to - 24V
Output Current up to 0.5A
General Description
The TS79M00 Series negative voltage regulators are identical to the popular TS7900 Series devices, except that they are
specified for only half the output current. Like the TS7900 devices, the TS79M00 Series 3-Terminal regulators are
intended for local, on-card voltage regulation.
Internal current limiting, thermal shutdown circuitry and safe-area compensation for the internal pass transistor combine
to make these devices remarkably rugged under most operating conditions. Maximum output current with adequate
heatsink is 500mA
This series is offered in 3-pin TO-220, TO-252 package.
Features
Standard Application
Output current up to 0.5A
No external components required

Note: Where xx denotes voltage option.
Absolute Maximum Rating
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.

z 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.
