MC79M00 Series

500 mA Negative Voltage

Regulators

are intended as complements to the popular MC78M00 series devices.

and −15 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 0.5 A.
