General Description:

 The CN2628 is a low-noise, linear regulator that delivers up to 1A of output current. The regulator maintain ±1% output accuracy over a wide input voltage range of 5.5V to 7V. The 520μA no-load supply current is independent of drop-out voltage.

The on-chip adaptive cell can adjust output current automatically based on the output capability of input power supply, so CN2628 is ideally suited for the solar-powered systems, or the applications that need to charge a cell phone with an input power supply whose output capability is limited.

The CN2628 adopts constant current mode for users to set the maximum output current flexibly. When the output is shorted, the output current will be limited to 10% of the constant current. Also CN2628 adopts temperature regulation instead of over-temperature protection, which will regulates the output current to limit the die temperature during high power operation or high ambient temperature.

The other features include on-chip soft-start, output over-current protection and chip enable, etc.

The CN2628 is available in a thermally enhanced 8-pin SOP package.
