Features:
The OMR9806 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.

In order to maintain regulation and stability speci-
fied 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 apply-
ing 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.
