They take input voltages from 2.8V to 22V and increase or decrease them as necessary, offering a typical efficiency of over 85% and typical continuous output currents between 1A and 3A \u003cstrong\u003e(\u003cem\u003ethis particular model is 1A\u003c\/em\u003e)\u003c\/strong\u003e. The flexibility in input voltage offered by this family of regulators is especially well-suited for battery-powered applications in which the battery voltage begins above 5V and drops below as the battery discharges. Without the typical restriction on the battery voltage staying above the required voltage throughout its life, new battery packs and form factors can be considered.\u003c\/p\u003e\n\u003cp\u003eThe regulators have an under-voltage lockout, output over-voltage protection and over-current protection.
