Features:
The OMR9805 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 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 re-
quiring low noise and higher efficiency.
Total dose and low dose capabilitiy to 200
Krad(Si) allows use in space applications
Ultra low dropout voltage of 0.4 volt signifi
cantly 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.
