DUAL 1A LOW DROPOUT POSITIVE REGULATOR
1 of 7
General Description
AP1120 series are low dropout positive regulator to provide
1A output current capability. The product is specifically designed
to provide well-regulated supply for low voltage IC applications
such as high-speed bus termination and low current 3.3V/2.5V or
3.3V/1.8V logic supply. AP1120 series are guaranteed to have
<1.3V dropout at full load current making it ideal to provide well
regulated outputs dual channels with up to 18V input supply.
