The IRUH33PA13B20 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 200Krad(Si) per MIL-STD-883, Method
1019 at 200Krad at high dose and 100Krad at 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 200Krad(Si) and low dose
capability to 30Krad(Si) allows use in
space applications
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
