Description

The RHFL6000A high-performance adjustable

positive voltage regulator provides exceptional

radiation performance. It is tested in accordance

with 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.
