DESCRIPTION

CN1117 is a series of lowdropout three-terminal regulators with a dropout of 1.3V at 1A load current. CN1117 features a lowstandby current 2mA.

Other than a fixedversion (VOUT = 1.2V, 1.8V, 2.5V, 3.3V, 5V, and 12V), CN1117 has anadjustable version, which can provide an output voltage from 1.25 to 12V withonly two external resistors.

CN1117 offers thermalshut down and current limit functions, to assure stability of chip and powersystem. Trimming technique is used to guarantee output voltage accuracy within ±2%. Other output voltage accuracy such as ±1% can be customized on demand.

CN1117 is available inSOT-223, power packages.
