Features:

The OMR9608 is a radiation hardened, ultra low dropout n Total dose and low dose capabilitiy to 1M

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.

Rad(Si) allows use in space applications

n Ultra low dropout voltage of 0.4 volts sig-

nificantly 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

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.

In order to maintain regulation and stability specified

additional input and output bulk capacitors are recom-

mended. 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 ce-

ramic capacitor.
