1A ULTRA LOW DROPOUT LINEAR REGULATOR  
AZ2940  
General Description  
Features  
The AZ2940 is a low dropout three-terminal regulator  
with a typical dropout of 280mV at 1A output current.  
·
·
Minimum Guaranteed Output Current: 1A  
Dropout Voltage at I =1A: 280mV  
OUT  
·
·
·
·
Output Accuracy: ± 1%  
Low Ground Current  
Internal Current Limit and Thermal Protection  
Reversed-battery and Reversed-lead Insertion  
Protection  
The AZ2940 provides current limit and thermal shut-  
down. On-chip thermal shutdown provides protection  
against any combination of high current and ambient  
temperature that would create excessive junction tem-  
peratures.  
·
Fast Transient Response  
The AZ2940 has 2.5V, 3.3V and 5.0V versions.  
The AZ2940 is available in the industry standard TO-  
220-3, TO-263-3 and TO-252-2 (1) power packages.

Figure 23. Typical Application of AZ2940  
Note: CIN is required if regulator is located far from power supply filter and is recommended to be 0.47µF or greater. To main-  
tain stability, COUT is recommended to be 2.2µF or greater. The ESR of this capacitor is critical, please see curve.
