DLA RHA Certified RADHard UltraLow Drop Out DCDC

DLA RHA Certified RAD-Hard Ultra-Low Drop Out DC-DC Voltage Regulators IR has introduced a series of high current, ultra-low dropout (ULDO) RAD-Hard hybrid linear voltage regulators available in Standard Microcircuit Drawings (SMD) with DLA Land Maritime certified RHA program for space applications including satellites and launch vehicles. HOME PAGE IRUH 3301 A 1 x. K IRUH 3301 A 2 x. K IRUH 330118 x. K IRUH 330125 x. K Features Silicon On Insulator (SOI) CMOS Regulator IC, CMOS Latch-up Immune, Inherently RAD-Hard Total Dose Capability up to 300 Krad (Si) (Condition A); Tested to 500 Krad (Si) ELDRS up to 100 Krad (Si) (Condition D) SEU Immune up to LET = 84 Me. V/(mg/cm 2) Space Level Screened Fast Transient Response Timed Latch-Off Over-Current Protection Internal Thermal Protection Adjustable Output as Low as 0. 8 V On/Off Control via Shut Down Pin, Power Sequencing Easily Implemented Available in two package styles, 5 -pin MO 0078 AA and 8 -pin flat pack with lead bend options Advantages • 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 -pin MO-078 AA and an 8 -pin 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 as well as outstanding TID and ELDRS testing in excess of 100 Krad (Si) with negligible effect on regulation tolerance. • 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.
