DESCRIPTION/ORDERING INFORMATION
µ A7900 SERIES
NEGATIVE-VOLTAGE REGULATORS
SLVS058H – JUNE 1976 – REVISED NOVEMBER 2006
• 3-Terminal Regulators • High Power-Dissipation Capability
• Output Current up to 1.5 A • Internal Short-Circuit Current Limiting
• No External Components • Output Transistor Safe-Area Compensation
• Internal Thermal-Overload Protection
This series of fixed-negative-voltage integrated-circuit voltage regulators is designed to complement Series
µ A7900 in a wide range of applications. These applications include on-card regulation for elimination of noise
and distribution problems associated with single-point regulation. Each of these regulators can deliver up to
1.5 A of output current. The internal current limiting and thermal shutdown features of these regulators
essentially make them immune to overload. In addition to use as fixed-voltage regulators, these devices can be
used with external components to obtain adjustable output voltages and currents and also as the power-pass
element in precision regulators.
