Description
The RHFL7913A adjustable is a high
performance Rad hard negative voltage regulator.
Available in FLAT-16 and new SMD5C hermetic
ceramic packages, it is specifically intended for
space and harsh radiation environments. It
provides exceptional electrical performances,
high speed and low dropout voltage. Input supply
ranges from - 3 V to - 12 V. It also provide logical
control / monitor functions (inhibit, output monitor,
short-circuit control) from/to external positive
voltage signals, while the entire RHFL7913A
adjustable analog functions are biased at
negative voltages with respect of ground pin. The
device is QML-V qualified with SMD 5962-02532.
