The OMR9604 is a radiation hardened, ultra low dropout
adjustable linear regulator designed specifically for space
applications. This product has been characterized to a
total ionizing dose of 1 M Rad (Si) per MIL-STD-883, Method
1019, Condition A at both high and low dose rates under
biased and unbiased conditions to account for ELDRS
effects in bipolar devices. The ultra low dropout voltage of
0.4V @ 3A makes the part particularly useful for applica-
tions requiring low noise and higher efficiency.
MO-078AA
Features:
n Total dose and low dose capabilitiy to 1M
Rad(Si) allows use in space applications
n Ultra low dropout of 0.4 volt significantly
reduces power consumption
n Low noise, higher efficiency
n Remote shutdown permits power
sequencing to be easily implemented
n Hermetic MO-078AA (TO-258AA) and 8-
lead flat pack ensure higher reliability
n K-level screened
