- Integrated over-current and thermal protection
- Enable pin control functionality
Applications
- Portable electronic devices
- Battery-powered systems
- General purpose power supply circuits
Procurement Notes
Verify the specific suffix YF5 corresponds to the SOT-23-5 package and tape-and-reel packaging configuration. Confirm that the 2.5V output variant matches the design requirements. Check RoHS compliance status and moisture sensitivity level prior to assembly planning. Ensure supplier documentation aligns with the official datasheet specifications for this exact part number.
Selection Notes
Select this component when a fixed 2.5V rail is required with moderate current demands up to 200mA. Consider the SOT-23-5 footprint for board layout constraints. Evaluate the input voltage headroom against the dropout characteristics. Verify that the enable pin logic levels are compatible with the controlling microcontroller or system interface.
Part Context
This LDO belongs to the RS3221 series from Runic Technology, designed for general-purpose power management tasks. The series offers various fixed voltage options and packaging styles to accommodate different application needs. The RS3221 family focuses on providing reliable regulation with built-in safety features for consumer and industrial electronics.
Replacement Considerations
Direct substitutes include other RS3221 variants with different fixed output voltages such as RS3221-3.0YF5 or RS3221-1.8YF5 if voltage adjustment is permissible. Cross-reference pinouts and thermal performance with alternative manufacturers' LDOs offering similar 200mA capabilities in SOT-23-5 packages.
