UA7805CKCSE3 developed by Texas Instruments is a member of fixed-voltage integrated-circuit voltage regulators. It can be used for a wide range of applications, including on-card regulation, portable devices, telecommunications, computing & servers. It is immune to overload based on the internal current-limiting and thermal-shutdown features. Moreover, this device can also be used with external components to obtain adjustable output voltages and currents and used as the power-pass element in precision regulators.
