Features:
The OMR9605 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.
