Rad-Hard 2.0A adjustable negative Vreg

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.

Key Features

  • 3 A low dropout voltage
  • Optional overtemperature and overcurrent protection
  • Adjustable overcurrent limitation
  • Load short circuit monitoring
  • Adjustable output voltage
  • Inhibit (ON/OFF) TTL-compatible control
  • Programmable output short-circuit current limitation
