General Description:

 The CN2626 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 2.7V to 6V, requiring only 300mV of input-to-output headroom at full load. The 410μA no-load supply current is independent of drop-out voltage.

The CN2626 has fixed output voltages of 2.5V, 3.0V, 3.1V, 3.3V, 4.0V, and 5V. The CN2626 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 CN2626 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 CN2626 is available in a thermally enhanced 8-pin SOP package.
