General Description

AP1122 is a low dropout positive fixed-mode 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 1.2V logic supply. AP1122 is also

well suited for other applications such as VGA cards. AP1122 is guaranteed to have lower than 1.3V dropout at full load current making it ideal to provide well-regulated outputs of 1.2 output voltage with 2.5V input voltage supply.
