Features:
n Total dose and low dose capabilitiy to 200
Krad(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
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.
