Features:
The OMR9800 is a radiation hardened, low dropout 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 unbi-
ased conditions to account for ELDRS effects in bipolar
devices. The ultra low dropout voltage of 1.1V @ 3A makes
the part particularly useful for applications requiring low
noise and higher efficiency.

Low dropout of 1.1 volts significantly re
duces power consumption
Low noise, higher efficiency
Remote shutdown permits power
sequencing to be easily implemented
Hermetic MO-078AA (TO-258AA) and 8-
