Positive adjustable LDO regulator with 1A maximum output current, offering an output voltage range of 1.4V to 20.5V. Features include ±1% accuracy, low dropout voltage (0.216V typical at 0.5A), and excellent line/load regulation. Operates from a 3V to 36V input, with typical PSRR of 78 dB and low output noise of 4.67 uVrms. Packaged in a 20-pin VQFN EP (5.15x5.15mm) for surface mounting, with integrated current limit and thermal shutdown protection.
