This series of fixed-voltage integrated-circuit voltage regulators is designed for a wide range of applications. These applications include on-card regulation for elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used with power-pass elements to make high-current voltage regulators. One of these regulators can deliver up to 100 mA of output current. The internal limiting and thermal-shutdown features of these regulators essentially make them immune to overload. When used as a replacement for a Zener diode-resistor combination, an effective improvement in output impedance can be obtained, together with lower bias current.
The µA78L00C and µA78L00AC series devices are characterized for operation over the virtual junction temperature range of 0°C to 125°C. The µA78L05AI device is characterized for operation over the virtual junction temperature range of −40°C to 125°C.
