    Apr 14, 2017 Radiation Hardened Low Dropout Adjustable Negative Voltage Regulator
    The radiation hardened ISL72991RH is a low dropout
    adjustable negative regulator with an output voltage range of
    -2.25V to -26V. The device features a 1A output current
    capability, an adjustable current limit pin (ILIM), and a
    shutdown pin (SD) for easy on/off control. Features The device incorporates unique circuitry that enables precision
    performance across the -55°C to +125°C temperature range
    and post-irradiation. Specifications across the full temperature
    range include an internal reference voltage of -1.25V +40mV/50mV (maximum), line regulation of ±25mV (maximum), and
    load regulation of ±15mV (maximum). The reference voltage is
    the ADJ to GND voltage. Wide input voltage range -3V to -30V Constructed with the Intersil dielectrically isolated Rad Hard
    Silicon Gate (RSG) BiCMOS process, these devices are immune
    to single event latch-up and have been specifically designed to
    provide highly reliable performance in harsh radiation
    environments. Dropout voltage (1A) . 1V (maximum) Applications Radiation environment
