MC7900 Series

1.0 A Negative Voltage

Regulators

The MC7900 series of fixed output negative voltage regulators are

intended as complements to the popular MC7800 series devices.

These negative regulators are available in the same seven−voltage

options as the MC7800 devices. In addition, one extra voltage option

commonly employed in MECL systems is also available in the

negative MC7900 series.

Available in fixed output voltage options from −5.0 V to −24 V,

these regulators employ current limiting, thermal shutdown, and

safe−area compensation − making them remarkably rugged under

most operating conditions. With adequate heatsinking they can deliver

output currents in excess of 1.0 A.

A common ground is required between the input

and the output voltages. The input voltage must

remain typically 2.0 V above more negative even

during the high point of the input ripple voltage.
