500 mA Positive Voltage Regulators MC78M00, MC78M00A, NCV78M00 Series Description 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. Internal current limiting, thermal shutdown circuitry and safe−area compensation for the internal pass transistor combine to make.

500 mA Positive Voltage Regulators MC78M00, MC78M00A, NCV78M00 Series Description 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. 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. Features • No External Components Required • Internal Thermal Overload Protection • Internal Short Circuit Current Limiting • Output Transistor Safe−Area Compensation • MC78M00A High Accuracy (±2%) Available for 5.0 V, 8.0 V, 12 V and 15 V • NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable • These are Pb−Free Devices 1.0 k 1.0 k Input 210 520 2.6 k 10 pF 300 3.6 k 6.4 k 6.7 V 16 k 100 1.0 k 200 3.0 k 5.6 k 40 pF 6.0 k 300 50 200 0.24 13 Output 2.0 k 3.9 k 6.0 2.8 k k GND This device contains 28 active transistors.
