• Provides a fixed 2.1 V output capable of delivering up to 600 mA load current
• Operates from a wide input voltage range of 2.5 V to 6 V
• Encapsulated in an extremely small WLP-5-8 footprint for space-constrained designs

Voltage Regulators - DC DC Switching Regulators Applications

• Portable electronic devices requiring compact power solutions
• Battery-powered equipment needing efficient step-down conversion
• Industrial applications operating within specified temperature ranges
• Point-of-load regulation in space-limited circuit boards

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix E0R-G against official Torex documentation to confirm the 2.1 V fixed output and WLP-5-8 packaging. Ensure compatibility with required input voltages between 2.5 V and 6 V. Confirm RoHS compliance status through manufacturer datasheets prior to integration. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.1 V output is required without external feedback resistors. The HiSAT-COT control allows for smaller inductors compared to conventional PWM controllers. Consider the 600 mA current limit for load requirements. The WLP-5-8 package is suitable for high-density PCB layouts where standard LGA or SOIC packages are too large.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9290 series of extremely small step-down DC/DC converters. The series emphasizes miniaturization and high efficiency using proprietary control techniques. Similar models in the family offer different fixed output voltages but share the same core architecture and package options. The B variant typically denotes specific performance characteristics within the product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other XC9290 variants with different fixed output voltages if system design permits adjustment. Verify pinout compatibility before replacing with other Torex buck converters. Ensure thermal performance matches the original application constraints.
