DESCRIPTION
A1118 is a dual channel low-dropout regulator that delivers a maximum current of 1A for each individual output. Typical dropout voltage at 1A load current is 1.3V. Each individual output voltage can be set independently as fixed voltage (e.g 1.2V, 1.8V, 2.5V, 3.3V, 5V) or adjustable output which can provide an output voltage from 1.25 to 12V with two external resistors. The output accuracy of each channel is set within 2% by trimming.
