AX1112
1.2V 350mA Low Dropout Linear Regulator
GENERAL DESCRIPTION
AX1112 is a low dropout positive fixed-mode regulator with minimum of 350mA 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 3.3V logic
supply. AX1112 is also well suited for other applications such as VGA cards. AX1112 is
guaranteed to have lower than 1.2V dropout at full load current making it ideal to provide
well-regulated outputs.
FEATURES
- Fixed 1.2V + 2% output voltage
- Fast transient response
- Output current limiting
- Built-in thermal shutdown
- Good noise rejection
- Packages: SOT-23-3L
