¡ñ ¡ù ¡ù ¡ù Application Simple high-efficiency step-down (buck) regulator On-card switching regulators Positive to negative converter Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed frequency oscillator. Available in a standard 5-lead TO-220 package with several different lead bend options, and a 5-lead TO-263 surface mount package. Other features include a guaranteed±4% tolerance on output voltage under specified input voltage and output load conditions, and±15% on the oscillator frequency.
