AP1122 is a 1A low dropout positive regulator
describe
The AP1122 is a low dropout positive fixed mode regulator with 1A output current capability. This product is specifically designed for low-voltage integrated circuit applications such as high-speed bus termination and low-current 1.2V logic power supplies. The AP1122 is also ideal for other applications such as VGA cards. The AP1122 is guaranteed to have a voltage drop of less than 1.3V at full load current, so it is ideal for a well-regulated output of 1.2 output voltage from a 2.5V input voltage supply.
