Features:  
The OMR9604 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.  
„
Total dose and low dose capabilitiy to 1M  
Rad(Si) allows use in space applications  
Ultra low dropout of 0.4 volt significantly  
reduces power consumption  
„
„
„
Low noise, higher efficiency  
Remote shutdown permits power  
sequencing to be easily implemented  
Hermetic MO-078AA (TO-258AA) and 8-  
lead flat pack ensure higher reliability

In order to maintain regulation and stability specified additional input and output bulk capacitors are  
recommended. Capacitors recommended above should be low ESR tantalums with tolerances of +/-  
20% max. Internal to the product are a 4.7uF input capacitor and a 4.7uF output capacitor in parallel with a  
0.33uF ceramic capacitor.  
Shutdown: The regulator can be shutdown by applying a voltage >1.6V to pin 4. The regulator will restart  
when the SHDN pin is pulled below the shutdown threshold of 1.0V. If remote shutdown is not required,  
pin 4 shold be connected to GND to insure a safe “off” state.
