IR has voltage regulators for space applications

Targeted at space applications such as satellites and launch vehicles, International Rectifier's new hybrid linear voltage regulators offer an ultra low dropout voltage of just 0.4V at full 3A load.

The high current, radiation hardened devices have been certified by the Defense Logistics Agency's Land and Maritime division, which guarantees their radiation performance down to the component level.

The regulators are suitable for point of load and post dc/dc power conversion, and are available in two industry standard package styles - a 5pins MO-078AA and an 8pins flat pack, each with multiple lead bend options.

In addition, the devices are said to provide fast transient response, timed latch off over current protection and internal thermal protection, as well as on/off control via shutdown pin.
