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

Note1: See thermal regulation specifications for changes in output voltage due to heating effects. Line and load
regulation are measured at a constant junction temperature by low duty cycle pulse testing. Load
regulation is measured at the output lead = 1/18” from the package.
Note2: Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power
dissipation is determined by the difference between input and output differential and the output current.
Guaranteed maximum power dissipation will not be available over the full input/output range.
Note3: Quiescent current is defined as the minimum output current required in maintaining regulation. At 12V
input/output differential the device is guaranteed to regulate if the output current is greater than 10mA.
Note4: Tap is connected to the multi-layer PCB cupper area 10mm*10mm.
