EL SEGUNDO, Calif. -- December 06, 2012

International Rectifier, IR^® (NYSE: IRF), a world leader in power management
technology, today introduced a series of high current, ultra-low dropout
(ULDO) RAD-Hard hybrid linear voltage regulators available in Standard
Microcircuit Drawings (SMD) for space applications including satellites and
launch vehicles.

The new Defense Logistics Agency (DLA), Land and Maritime certified voltage
regulators are also included in IR’s Radiation Hardness Assurance (RHA)
program certified by DLA Land and Maritime division (formerly DSCC) that
guarantees the devices’ radiation performance down to the component level.

The space level screened devices, designed for point-of-load and post DC-DC
power conversion, offer a low dropout voltage of only 0.4 V at full 3 A load.
They are available in two industry standard package styles, a 5-pins MO-078AA
and an 8-pins flat pack, each with multiple lead bend options. The new
regulators feature a Silicon On Insulator (SOI) CMOS Regulator IC, latch-up
and SEU immunity with LET of 84^2/mg, as well as outstanding TID rating
of 300 Krad(Si) and ELDRS testing in excess of 100 Krad(Si) with negligible
effect on regulation tolerance. In addition, the devices provide fast
transient response, timed latch-off over-current protection and internal
thermal protection, and on/off control via shutdown pin.

“In addition to offering DLA-certification, these voltage regulators using a
standard microcircuit drawing (SMD) part number are included in IR’s RHA
program to offer customers a highly reliable, government approved solution.
The new devices augment IR’s space hybrid product line and complement our
DC-DC converters to provide a one-stop power management solution supplier for
the space community,” said Tiva Bussarakons, Marketing Director for IR’s HiRel
DC-DC Converter Products.

Design analyses including worst case (WCA), electrical stress, thermal,
stability with respect to additional output capacitors, and DFMEA are
available at no-charge for standard models.
