UPC7924AHF

DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT µPC7900A Series THREE TERMINAL NEGATIVE VOLTAGE REGULATOR DESCRIPTION µPC7900A series are monolithic three terminal negative regulators which employ internally current limiting, thermal shut down, output transistor safe operating area protection make them essentially indestructible. They are intended as fixed voltage regulators in a wide range of application including local on card regulation for elimination of distribution problems associated wide single point regulation. FEATURES Wide operation temperature range. TA: –30 ˚C to +85 ˚C Good load regulation. 7 mV TYP. (250 mA ≤ IO ≤ 750 mA): µPC7905AHF Low noise.
