Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DDCT' corresponds to the SOT-23-THIN-5 package and tape-and-reel delivery format. Confirm that the fixed 1.8 V output aligns with system requirements, as alternative voltages exist within the TPS62222 family. Ensure compatibility with the specified 2.7 V to 5.5 V input range for the target application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8 V rail is required without external feedback resistor programming. It is suitable for applications prioritizing board space efficiency due to the SOT-23-THIN-5 package. Consider the 400 mA current limit and 1.25 MHz frequency when designing the output filter components.
