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

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.
