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.
