Features:

The OMR9608 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 voltage of 0.4 volts sig-

nificantly 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.
