RHFL4913A
SMD5C:
5-connection SMD
Description
The RHFL4913A 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 RHFL4913A is QML-V qualified, DSCC SMD
#5962F02524.
