TS7900A series

3-Terminal Fixed Negative Output Voltage Regulator

TO-263

Pin assignment:

1. Ground

2. Input

Voltage Range - 5V to - 24V

Output Current up to 1.5A

3. Output

(Heatsink surface

connected to Pin 2)

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

Standard Application

ꢀ

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

Ordering Information

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.

Part No.

XX = these two digits of the type number indicate voltage.

* = Cin is required if regulator is located an appreciable

distance from power supply filter.
