Dual 1A Low Dropout Positive Regulator

Features

General Description

AP1121 series are low dropout positive regulator

with minimum of 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 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.

• 1.3V maximum dropout at full load current

• Fast transient response

• Output current limiting for each channel.

• Built-in thermal shutdown each channel.

• Good noise rejection

• Dual output ch1=3.3V, ch2=2.5V

(1.8V for B version)

• Pb-Free Packages: SOP-8L

Applications

• PC peripheral

• Communication
