RHFL4913XX15：Rad-Hard 1.5 Volt Fixed Positive Vreg
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.
