Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix PR-G corresponds to the SOT-89-5 package configuration. Confirm that the CE pin is properly biased to either VIN or VSS during operation to prevent undefined states. Ensure the ordering code matches the required output voltage tolerance and operating temperature range specifications.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 2.5V output is required with high accuracy and low quiescent current. The SOT-89-5 package offers a balance between thermal performance and board space. Consider the internal phase compensation feature if minimizing external capacitor count is a priority for the design.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the XC6701 series of high-speed voltage regulators.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes within the same series include other XC6701B variants with different output voltages or packages, such as XC6701BxxMR-G for SOT-25. Cross-series replacements like XC6701AxxPR-G are available but offer an extended temperature range up to 105℃.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What happens if the CE pin is left open?

Leaving the CE pin open results in an undefined operational state. For stable operation, the CE pin must be connected to either VIN or VSS.

Is an output capacitor required for stability?

No, the XC6701 series features internal phase compensation, allowing it to operate stably even without an output capacitor, though one is recommended for transient response.
