Integrated 5V linear regulator with low dropout voltage (input voltage - output voltage)

AMS1117 is a series of low dropout three-terminal regulators with a dropout of 1.3V at 1A load current. AMS 1117 features a very low standby current 2mA compared to 5mA of a competitor. 
AMS 1117 offers thermal shut down and current limit functions, to assure the stability of chip and power system.

And it uses the trimming technique to guarantee output voltage accuracy within 2%.

Other output voltage accuracy can be customized on demand, such as 1% 

1: input: DC 4.5 V-7 V (input voltage must be more than to output voltage high 1 V above.)
2: output: 3.3 V, 800 mA (load current can’t more than 800 mA)
3 : PCB size:8.6* 12.3 mm

Attention :
1: Boost modules or buck module indicate the operating voltage, Please do not exceed operating voltage, or it will be damaged easily!
2: Boost module output voltage can only be greater than or equal to the input voltage, cannot be less than the input voltage!
3: Buck module input voltage must be higher than the output voltage of 1.5V or 2V, otherwise it can not output enough power!
4: Automatic Adjustable Boost or Buck module has start voltage and limit working voltage, Please do not exceed them, or it will be damaged easily!
5: Cannot reverse polarity, or it will be a short circuit or will be born easily!
