The LM9073 is a high performance voltage regulator system with operational and protection features that address many requirements of automotive applications. Two regulated outputs are provided. The main regulator provides a precision 2% tolerance 5V output at 700mA with a low dropout characteristic. The second output, an External Supply regulator, provides a 5V output with 2% tolerance for load currents up to 100mA. This External Supply output is fully protected from short circuit to ground or the unregulated input supply (ignition or battery potentials in automotive applications) which makes it suitable for powering remotely located load circuits or sub-systems.
