Manufacturer Part Number
IRUH33PA13A1MK
Description
Ultra Low Dropout Positive Adjustable Linear Regulator +3.3Vin at 3.0A
Manufacturer
IRF [International Rectifier]
Datasheet
Ultra Low Dropout
Positive Adjustable Linear Regulator
The IRUH33PA13A1M 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.
