Frequently asked questions
What is the price of AMS1117-3.3 3.3V 1A LDO Voltage Regulator SOT-89 in Egypt?
AMS1117-3.3 3.3V 1A LDO Voltage Regulator SOT-89 currently costs between 4.5 and 7.5 EGP across 2 offers in Egypt.
Where can I buy AMS1117-3.3 3.3V 1A LDO Voltage Regulator SOT-89 in Egypt?
AMS1117-3.3 3.3V 1A LDO Voltage Regulator SOT-89 is available from Makers Electronics and UGE. Compare the offers above to find the best price.
What minimum input voltage do I need?
The dropout is about 1.15 V at 1 A, so at full load the input must be at least roughly 1.15 V above 3.3 V, about 4.5 V or more. Keep the input below the 18 V maximum.
Does it need input and output capacitors?
Linear regulators like this normally need input and output capacitors for stable operation. Follow the recommended capacitor values in the datasheet for this exact part before connecting a load.
