The UA78L series can be used for on-card regulation to eliminate the noise and distribution problems associated with single-point regulation. The UA78L can also be used with power-pass elements to make high-current voltage regulators. The UA78L series regulators can deliver up to 100 m A of output current. Additionally, the UA78L does not need an external capacitor for stable operation across the load current range. The internal current-limiting and thermal-shutdown features of these regulators help protect the device from overload. For the legacy chip, the UA78L00C and UA78L00AC series are characterized for the junction temperature range of 0°C to +125°C and the UA78L05AI device is characterized for the operating junction temperature range of - 40°C to +125°C. For the new chip, the UA78L series is characterized for the junction temperature range of - 40°C to +125°C.
