Rad-hard adjustable positive voltage regulator
Datasheet - production data
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.
7 / $ )
The RHFL4913A features exceptional radiation
R06QQF'Q R
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
Features new SMD5C hermetic ceramic package, and the
QML-V die is specifically designed for space and
Operating input voltage from 3 V to 12 V
harsh radiation environments. It operates with an
Adjustable output voltage input supply of up to 12 V. The RHFL4913A is
QML-V qualified, DSCC SMD #5962F02524.
