Negative adjustable linear voltage regulator IC, offering an output voltage range of -1.25V to -40V with a maximum output current of 1.5A. Features include ±1% accuracy, 0.02%/V line regulation, and 0.5% load regulation. This through-hole component is housed in a TO-257AA metal package with 3 pins and a tab, designed for efficient heat dissipation with a junction-to-case thermal resistance of 5°C/W. Integrated current limit and thermal shutdown protection ensure reliable operation across an extended temperature range of -55°C to 150°C.
