TS7900A series
3-Terminal Fixed Negative Output Voltage Regulator
TO-263
Pin assignment:
1. Ground
2. Input
3. Output
(Heatsink surface
connected to Pin 2)
Voltage Range - 5V to - 24V
Output Current up to 1.5A
General Description
The TS7900A series of fixed output negative voltage regulators are intended as complements to the popular TS7800A
series device. These negative regulators are available in the same seven-voltage options as the TS7800A devices.
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 sink
they can deliver output currents in excess of 1.5 ampere.
This series is offered in 3-pin TO-220, TO-263 package.
Features
Output current up to 1.5A
No external components required
Internal thermal overload protection
Internal short-circuit current limiting
Output transistor safe-area compensation
Output voltage offered in +/-2% tolerance

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.

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.
