Three-Terminal Medium Current 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.

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.

? 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

MC78M05BDTG屬于集成電路（IC） > 線性 + 開關穩(wěn)壓器。安森美半導體公司制造生產的MC78M05BDTG穩(wěn)壓器 - 線性線性穩(wěn)壓器用于提供穩(wěn)定的輸出電壓，無論負載電流、輸入電壓或環(huán)境因素如何變化，這些輸出電壓通常都要保持不變。它們的工作原理要求輸入電壓維持在高于所需的輸出電壓，而且要超出某個最小量，并且在工作時會將輸入端的任何多余電壓轉換為熱量。對于大多數(shù)應用而言，雖然這種穩(wěn)壓器的效率低于開關模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應用。
