DESCRIPTION
The OMR9601 is a radiation hardened, ultra low dropout linear regulator designed
specifically for space applications. This product has been characterized to a total ionizing
dose of 1M 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 ELDRE 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.
