The IRUH50PA23B1M 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 1.0Mrad(Si) per MIL-STD-883, Method
1019 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 1.0Mrad(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 = 1 x 109 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 Space Level Screened
n This part is also available in 8-Lead Flat Pack
Package as IRUH50PA23A1M
