It is designed to generate a clean negative rail from a raw negative input up to -35V maximum. With a PSRR of 60dB at 120Hz, this part attenuates mains-frequency ripple on the input by a factor of 1000, making it suitable for powering analog circuits such as op-amps, ADCs, and audio stages that require a low-noise negative supply. Built-in protection features include over-temperature shutdown and short-circuit current limiting, which guard against load faults and thermal runaway in confined enclosures. ## Dropout voltage and quiescent current for BOM planning The typical dropout voltage is 1.4V at 1A output, meaning the input must be at least -6.4V to maintain regulation at full load. This is a standard figure for a three-terminal negative regulator of this era and class. Quiescent current is 3 mA typical, which is the current drawn by the regulator's internal bias circuitry. It does not vary significantly with load, so the total input current is the output current plus this 3 mA overhead. For industrial or automotive environments requiring -40°C operation, a different negative regulator with a wider temperature grade would be needed. No end-of-life notification or successor has been issued for this order code.
