Description
AP1122 is a low dropout positive fixed-mode regulator with
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.
