Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DRYR' against the manufacturer datasheet to confirm the reel packaging format and tape-and-reel specifications. Ensure the component matches the required 6-SON footprint and pinout dimensions for PCB layout compatibility. Cross-reference the RoHS compliance status and assembly site information provided in the latest production change notices before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.2 V output is required for space-constrained designs. The 3 MHz switching frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. It is suitable for applications powered by single lithium-ion cells or two alkaline batteries, offering efficient operation across the entire load range without requiring external compensation components.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS6223x series of ultra-small step-down converters designed for portable applications. It shares the same core architecture and package style as variants like the TPS62230 and TPS62231, differing primarily in their fixed output voltage settings. The series is optimized for minimal component count and board area reduction in modern electronic devices.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct functional substitutes within the same family include TPS62230DRYR (1.0 V output) and TPS62231DRYR (1.8 V output). These parts share identical pinouts, packages, and electrical characteristics except for the regulated output voltage. Verify that the target application can tolerate the alternative voltage levels before substitution.
