Description
The IRUH3301A1 is a space qualified, ultra low dropout
linear regulator designed specifically for applications
requiring high reliability, low noise and radiation hardness.
The output voltage can be adjusted to a low 0.8V with a
droput voltage of 400mV at the full rated current of 3.0
Amps.
