The UA78L series of fixed-voltage, integrated-circuit voltage regulators is designed for a wide range of applications. The UA78L series supports a wide range of input voltages and can deliver 100 mA of load current.

This device features internal current-limiting and thermal shutdown mechanisms. To provide reliable operation across wide V_I ranges, the current-limiting mechanism modulates the load current capacity both by monitoring the V_O level and the difference between the V_I and V_O voltage levels. The operating ambient temperature range of the device is –40°C to +125°C for all variants of the new chip.
