DESCRIPTION/ORDERING INFORMATION

µA7900 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

µA7900 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.
