1. Introduction:
The AMS1117 is a forward low dropout regulator with 1.2V dropout at 1A .
The AMS1117 is available in two versions : a fixed output version and an adjustable version with fixed output voltages of 1.5V , 1.8V , 2.5V , 2.85V , 3.0V , 3.3V , 5.0V with 1 % accuracy; fixed output voltages of 1.2 The accuracy of V is 2% .
The names are:
AMS1117 integrates thermal protection and current limiting circuit , it is the best choice for battery powered and portable computers
2. Electrical Characteristics
3. Package and pin distribution
4. Temperature stability:
It can be seen that -25 to 25 degrees is basically no error
