MC78M00, MC78M00A

Series

500 mA Positive Voltage

Regulators

The MC78M00/MC78M00A Series positive voltage regulators are

identical to the popular MC7800 Series devices, except that they are

specified for only half the output current. Like the MC7800 devices,

the MC78M00 three−terminal regulators are intended for local,

on−card voltage regulation.

MARKING

DIAGRAMS

Internal current limiting, thermal shutdown circuitry and safe−area

compensation for the internal pass transistor combine to make these

devices remarkably rugged under most operating conditions.

Maximum output current, with adequate heatsinking is 500 mA.
