Features:

The OMR9807 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 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 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.
