Frequently asked questions
What is the price of AMS1117-3.3 Low-Dropout Voltage Regulator 3.3 V 1 A SOT-223 in Egypt?
AMS1117-3.3 Low-Dropout Voltage Regulator 3.3 V 1 A SOT-223 currently costs between 5 and 6 EGP across 2 offers in Egypt.
Where can I buy AMS1117-3.3 Low-Dropout Voltage Regulator 3.3 V 1 A SOT-223 in Egypt?
AMS1117-3.3 Low-Dropout Voltage Regulator 3.3 V 1 A SOT-223 is available from Microohm and Most Electronics. Compare the offers above to find the best price.
What input voltage should I supply for a 3.3 V output at 1 A?
The maximum dropout is 1.3 V at full load, so the input should be at least about 4.6 V (3.3 V + 1.3 V) to hold 3.3 V at 1 A. At lower currents the required headroom is smaller.
Do I need capacitors with this regulator?
Yes, the datasheet recommends input and output capacitors for stable operation. Follow the datasheet's recommended capacitor types and values for your application.
