AMS1117  
1A Adjustable/Fixed Low Dropout Linear Regulator  
General Description  
Key Features  
The AMS1117-ADJ and AMS1117-1.2,-1.5,-1.8,-2.5,-2.85,  
-3.3 and-5 are low dropout three-terminal regulators with  
1A output current capability. These devices have been  
optimized for low voltage where transient response and  
minimum input voltage are critical. The 2.85V version is  
designed specifically to be used in Active Terminators for  
SCSI bus.  
- Low dropout voltage  
- Load regulation: 0.2% typical  
- Optimized for Low Voltage  
- On-chip thermal limiting  
- Standard SOT-223 and TO-252 packages  
- Three-terminal adjustable or fixed low dropout  
1.2V,1.5V,1.8V, 2.5V, 2.85V, 3.3V, 5V. Regulators  
On-chip thermal limiting provides protection against any  
combination of overload and ambient temperatures that  
would create excessive junction temperatures.  
Applications  
- Active SCSI terminators  
- High efficiency linear regulators  
- Post regulators for switching supplies  
- Battery chargers  
- 12V to 5V linear regulators  
-Motherboard clock supplies  
Unlike PNP type regulators where up to 10% of the output  
current is wasted as quiescent current, the quiescent cur-  
rent of the AMS1117 flows into the load, increasing effi-  
ciency.  
The AMS1117 series regulators are available in the indus-  
try-standard SOT-223 and TO-252 power packages.  
Typical Application

Notice: The distance between Vout pin and Capacitor should not exceed 4cm for excellent performance
