EZ1117 & EZ1117A  
0.8 & 1.0 Amp Positive  
Voltage Regulators  
POWER MANAGEMENT  
Description  
Features  
The EZ1117 series of high performance positive voltage  
regulators are designed for use in applications requiring  
low dropout performance at up to 0.8A (1A for EZ1117A).  
u Low dropout performance: 1.2V max. for EZ1117,  
1.3V max. for EZ1117A  
u Full current rating over line and temperature  
u Fast transient response  
Additionally, the EZ1117 series provides excellent  
regulation over variations in line, load and temperature.  
Outstanding features include low dropout performance  
at rated current, fast transient response, internal  
current limiting and thermal shutdown protection of the  
output device.  
u +2% total output regulation over line, load and  
temperature  
u Adjust pin current max 90µA over temperature  
u Fixed/adjustable output voltage  
u Line regulation 0.2% max.  
u Load regulation 0.4% max.  
u SOT-223 and TO-263 packages  
The EZ1117 series of three terminal regulators offer fixed  
and adjustable voltage options available in the space  
saving SOT-223 and TO-263 packages.  
Applications  
u Low voltage microcontrollers  
u Switching power supply post-regulation
