DATA SHEET www.onsemi.com 500 mA Positive Voltage Regulators 4 MC78M00, MC78M00A, 2 1 NCV78M00 Series 3 1 2 3 Description DPAK3 TO220 The MC78M00/MC78M00A Series positive voltage regulators are DT SUFFIX T SUFFIX identical to the popular MC7800 Series devices, except that they are CASE 369C CASE 221AB specified for only half the output current. Like the MC7800 devices, the MC78M00 threeterminal regulators are intended for local, oncard voltage regulation. MARKINGDIAGRAMS Internal current limiting, thermal shutdown circuitry and safearea 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.
