3-Terminal Fixed Negative Voltage Regulators

Pin Arrangement

Description

These voltage regulators are intended as complements

to the popular MC78xx Series devices. These negative reg-

ulators are available in the same seven-voltage options as

the MC78xx devices. In addition, one extra voltage

option commonly employed in MECL systems is also

available in the negative MC79xx Series.

TO-220

1. Ground

2. Input

3. Output

Available in fixed output voltage options from –5.0 to –24

volts, these regulators employ current limiting, thermal shut-

down, and safe-area compensation – making them remark-

ably rugged under most operating conditions. With adequate

heatsinking they can deliver output currents in excess of

1.5 ampere.

Notes:

Mechanical Data

Case: TO-220 Package

A common ground is required between the input and the output voltages.

The input voltage must remain typically 2.0V more negative even during

the high point on the input ripple voltage.

xx = these two digits of the part number indicate output voltage.

Weight: approx. 2.24g

Cin is required if regulator is located an appreciable distance from power

supply filter.

Case outline is on the back page

Co improves stability and transient response.
