RHFL7913A Rad-hard adjustable negative voltage regulator Features 3 A low dropout voltage Optional overtemperature and overcurrent protection Adjustable overcurrent limitation Load short circuit monitoring Adjustable output voltage SMD5C: FLAT-16 5-connection SMD Inhibit (ON/OFF) TTL-compatible control Programmable output short-circuit current limitation Remote sensing operation Description Rad-hard: sustains 300 krad in Mil-1019.7 at High & ELDRS low dose rate conditions The RHFL7913A adjustable is a high Heavy ions, SEL immune at 68 MeV/cm/mg performance Rad hard negative voltage regulator. LET ions 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.
