MC7900 - 1.0 A Negative Voltage Regulators

1 Semiconductor Components Industries, LLC, 2013 July, 2013 Rev. 181 Publication Order Number: MC7900 /DMC7900 A Negative VoltageRegulatorsThe MC7900 series of fixed output Negative Voltage Regulators areintended as complements to the popular MC7800 series Negative Regulators are available in the same seven voltageoptions as the MC7800 devices. In addition, one extra Voltage optioncommonly employed in MECL systems is also available in thenegative MC7900 in fixed output Voltage options from V to 24 V,these Regulators employ current limiting, thermal shutdown, andsafe area compensation making them remarkably rugged undermost operating conditions. With adequate heatsinking they can deliveroutput currents in excess of A. No External Components Required Internal Thermal Overload Protection Internal Short Circuit Current Limiting Output Transistor Safe Area Compensation Available in 2% Voltage Tolerance (See Ordering Information) Pb Free Package May be Available.
