RHFL6000A：Rad-Hard 2.0 A adjustable positive voltage regulator

The RHFL6000A high-performance adjustable positive voltage regulator provides exceptional radiation performance. It is tested in accordance with mil MIL-STD-883J Method 1019.9, in ELDRS conditions. The device is available in the FLAT- 16P, a hermetic ceramic package, and the QML-V die is specifically designed for space and harsh radiation environments. A dedicated internal circuitry is implemented for absorbing output transients during SET events. The operating input voltage goes from 2.5 V to 12 V.
