400mA Low Dropout Linear Regulator
GENERAL DESCRIPTION
AX1113 is a low dropout positive adjustable or fixed-mode regulator with minimum of
400mA 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 5V logic supply. AX1113 is also well suited for other applications such as
VGA cards. AX1113 is guaranteed to have lower than 1.2V dropout at full load current.
FEATURES
- 3-Terminal Adjustable or Fixed 1.8V, 3.3, 5.0V
- Fast transient response
- Output current limiting
- Built-in thermal shutdown
- Good noise rejection
- Packages: SOT89-3L
