The AT1796 series of regulators are step-down (buck) DC/DC converter, capable of driving a 3A load with excellent line and load regulation. Requiring a minimum number of external components, these regulators are simple to use . The AT1796 series operates at a switching frequency of 150kHz.Available in a standard 5-lead TO-263 surface mount package. It include a guaranteed 4% tolerance on output voltage under specified input voltage and output load conditions, and 15% on the oscillator frequency.
