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.
