AP1120 DUAL 1A LOW DROPOUT POSITIVE REGULATOR General Description Features AP1120 series are low dropout positive regulator to provide 1.3V maximum dropout at full load current 1A output current capability. The product is specifically designed Fast transient response to provide well-regulated supply for low voltage IC applications Output current limiting for each channel such as high-speed bus termination and low current 3.3V/2.5V or Built-in thermal shutdown each channel 3.3V/1.8V logic supply. AP1120 series are guaranteed to have Good noise rejection <1.3V dropout at full load current making it ideal to provide well Dual output ch1=3.3V, ch2=2.5V regulated outputs dual channels with up to 18V input supply.
