简 介:MC7900 Series 1.0 A Negative Voltage Regulators
The MC7900 series of fixed output negative voltage regulators are intended as complements to the popular MC7800 series devices. These negative regulators are available in the same sevenvoltage options as the MC7800 devices. In addition, one extra voltage option commonly employed in MECL systems is also available in the negative MC7900 series. Available in fixed output voltage options from 5.0 V to 24 V, these regulators employ current limiting, thermal shutdown, and safearea compensation making them remarkably rugged under most operating conditions. With adequate heatsinking they can deliver output currents in excess of 1.0 A. No External Components Required Internal Thermal Overload Protection Internal Short Circuit Current Limiting Output Transistor SafeArea Compensation Available in 2% Voltage Tolerance (See Ordering Information) PbFree Package May be Available.
