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

Verify that the specific part number XC6220A08BER-G matches the required 0.8V output voltage and USP-6C package configuration. Confirm the 'A' designation indicates no CE pull-down resistor and no CL discharge feature, as these vary across the series. Ensure compliance with EU RoHS standards and lead-free requirements specified by the '-G' suffix before finalizing procurement orders.

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

Select this component when a fixed 0.8V output is required with high accuracy. The 'A' type is suitable for designs where the CE pin logic is managed externally without internal pull-down resistors. Consider the Green Operation feature for applications requiring efficient power management under varying load conditions. Verify that the application environment stays within the -40℃ to 85℃ operating temperature range.

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

This part belongs to the XC6220 series of 1A CMOS LDO regulators known for low noise and high speed performance. The series offers selectable output voltages in 0.05V increments. The XC6220A variant specifically lacks internal CE pull-down resistors and CL discharge transistors, distinguishing it from B, C, and D types which offer different standby and discharge characteristics.

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

Direct substitutes within the same series include other XC6220 variants with different output voltages or package options, such as XC6220x08ER-G for alternative packages. Cross-series replacements require matching input voltage ranges, current capabilities, and package footprints. Verify functional compatibility regarding CE pin behavior and discharge features when substituting.

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

What is the difference between the XC6220A and XC6220B types?

The XC6220A type does not have a CE pull-down resistor or CL auto-discharge function. In contrast, the XC6220B type includes CL auto-discharge but lacks the CE pull-down resistor. This affects how the output behaves when the IC is turned off.

How does the Green Operation function work?

Green Operation automatically switches the regulator between High Speed (HS) mode and Power Save (PS) mode based on the output current level. It transitions to PS mode during light loads to reduce supply current and returns to HS mode during heavy loads to maintain performance.
