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
and Maritime certified RHA program for space
applications including satellites and launch
vehicles.

(Condition A); Tested to 500Krad (Si)
 ELDRS up to 100Krad (Si) (Condition D)
 SEU Immune up to LET = 84MeV/(mg/cm2)
 Space Level Screened
 Fast Transient Response
 Timed Latch-Off Over-Current Protection
 Internal Thermal Protection
 Adjustable Output as Low as 0.8V
 On/Off Control via Shut Down Pin, Power
Sequencing Easily Implemented
 Available in two package styles, 5-pin MO0078AA 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 0.4V at full 3A
load. They are available in two industry
standard package styles, a 5-pin MO-078AA 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 100Krad (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.
