The IRUH33P253A1M 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
capability 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 8-lead flat pack ensures higher
reliability
n Space Level Screened
n This part is also available in MO-078 Package
as IRUH33P253B1M
