Description
The device is a high performance radiation
hardened LDO regulator, suitable for output
current up to 3 A (TO-257 and SMD.5 versions).
The operating input voltage range is from 3 V to
12 V. The device has been specifically designed
for harsh radiation environments, such as
aerospace applications.
Integrated overtemperature protection, adjustable
overcurrent protection and monitoring offer a high
level of robustness.
It is available in Flat-16, SMD.5 and TO-257
hermetic packages.
