Description
The
RHFL4913A
is a high-performance adjustable positive voltage regulator, able to
provide 2 A of maximum current in FLAT-16 package (3 A in the SMD5C package)
from an input voltage ranging from 3 V to 12 V, with a typical dropout voltage of 350
mV.
The
RHFL4913A
features exceptional radiation performances. 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 SMD5C hermetic ceramic package, and the QML-V
die is suitable for harsh environments. It operates with an input supply of up to 12 V.
The
RHFL4913A
is QML-V qualified, DSCC SMD #5962F02524.
