AX1212A
1.2V Output 1A LOW Dropout Linear Regulator
GENERAL DESCRIPTION
AX1212A 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. AX1212A is also well suited for other applications such as VGA
cards. AX1212A is guaranteed to have lower than 1.5V dropout at full load current making
it ideal to provide well-regulated outputs of 1.2V with 2.6V to 12V input supply.
FEATURES
- Fixed 1.2V + 2% output voltage
- 1.5V maximum dropout at full load current
- Low-ESR Ceramic Capacitor (MLCC) Required for Stability
- Fast transient response
- Output current limiting
- Built-in thermal shutdown
- Good noise rejection
- Pb-Free Packages: SOT223, TO252
