Features:
The OMR9805 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 200 Krad (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 requiring low noise and higher efficiency.
