Description
The RHFL4913 high-performance adjustable
positive voltage regulator provides exceptional
radiation performance. It is tested in accordance
with Mil Std 883E Method 1019.6, in ELDRS
conditions.
The device is available in the Flat-16 and the new
SMD5C hermetic ceramic package, and the
QML-V die is specifically designed for space and
harsh radiation environments. It operates with an
input supply of up to 12 volts.
The RHFL4913 is QML-V qualified, DSCC SMD
#5962F02524.
