General Description
AX1212 is a low dropout positive 1.2V output regulator with minimum of 1A output current capability. The
product is specifically designed to provide well-regulated supply for low voltage IC applications. AX1212 is also
well suited for other applications such as VGA cards. AX1212 is guaranteed to have lower than 1.4V dropout
at full load current making it ideal to provide well-regulated outputs of 1.2V with 2.6V to 12V input supply.
