Adjustable negative linear voltage regulator, offering output voltages from -1.25V to -37V with a maximum output current of 1.5A. Features include current limit, safe area protection, short circuit protection, and thermal protection. This surface-mount device utilizes a D2PAK (TO-263) package with gull-wing leads, a 3-pin configuration, and a tab for enhanced thermal performance. Operating within a -0°C to 125°C temperature range, it boasts a typical PSRR of 77 dB and a junction-to-case thermal resistance of 4°C/W.
