“Green” Products (Note 1)
Applications
AP1121 is a 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. AP1121 is a 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.
• PC peripheral
• Communication
