General Description
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.
FEATUREs
• 1.3V maximum dropout at full load current
• Fast transient response
• Output current limiting for each channel
• Built-in thermal shutdown for each channel
• Good noise rejection
• Dual output ch1 = 3.3V, ch2 = 2.5V
(ch2 = 1.8V for version B)
• SOP-8L: Available in “Green” Molding Compound (No
Br, Sb)
• Lead Free Finish/ RoHS Compliant for Lead Free and
“Green” Products (Note 1)
APPLICATIONs
• PC peripheral
• Communication
