Features:
The OMR9607 is a radiation hardened, ultra low dropout
linear regulator designed specifically for space applica-
tions. This product has been characterized to a total ioniz-
ing 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 applications re-
quiring low noise and higher efficiency.
