Other features include a transient response time of 2 µs, tolerance current limiting at ratings of 0.8A, 1.4A, or 2A, over-temperature and short-circuit protection, controlled rise-time and under-voltage lockout functionality, an automatic output discharge function to provide controlled discharge of disabled output capacitor voltage, and a 7-ms deglitch time on the power switch’s fault report flag.
