AP1122
„ 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.
