The UA78L00 series of fixed-voltage linear 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 as well as for voltage regulation in major appliances. 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 help to protect the device from overload.
The UA78L00C and UA78L00AC series devices are characterized for operation over the virtual junction temperature range of 0°C to 125°C. The UA78L05AI device is characterized for operation over the virtual junction temperature range of –40°C to 125°C.
