The OMR9601SC is a space qualified, ultra low dropout
linear regulator designed specifically for space
applications. This product has been characterized to a total
ionizing dose of 1.0 Mrad (Si) per MIL-STD-883, Method
1019, Condition D 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
requiring low noise and higher efficiency.
Features:
n Total dose to 1.0 Mrad (Si) and low dose
capabilitiy to 500 krad (Si) allows use in
space applications
n Single Event latchup Immune
LET= 84 MeV/(mg/cm2)
Fluency = 1x109 ions/cm2
n Low noise, higher efficiency
n Ultra low dropout voltage of 0.4V@ 3A out
significantly reduces power consumption
n Remote shutdown permits power
sequencing to be easily implemented
n Hermetic MO-078AA (TO-258AA)
pack ensures higher reliability
n K-level screened
n This part is also available in
8-Lead Flat Pack Package as OMR9601SF
