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

Verify the specific ordering suffix ER-G corresponds to the USP-6C package type as defined in the manufacturer's classification guide. Confirm that the B-series designation indicates the presence of the CL auto-discharge feature required for your application. Ensure compliance with EU RoHS standards and lead-free requirements specified by the -G suffix before finalizing procurement specifications.

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

Select this component when a fixed 0.9V output is required with high efficiency under varying load conditions. The Green Operation feature makes it suitable for battery-powered devices where standby current reduction is critical. Verify that the required output capacitor value aligns with the stability recommendations for the 0.9V output voltage setting to ensure phase compensation stability.

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

This part belongs to the XC6220 series of 1A LDO regulators. The 'B' in the model number denotes a standard version with CL auto-discharge but without a CE pull-down resistor. The '09' indicates the nominal output voltage of 0.9V. The 'ER-G' suffix specifies the USP-6C package and environmental compliance. This series is designed for applications requiring low noise and high precision power supply regulation.

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

How does the Green Operation function affect the supply current?

The Green Operation function automatically switches the IC between High Speed (HS) mode and Power Save (PS) mode based on the output current level. In PS mode, the typical supply current drops to 8μA, significantly reducing power consumption during light load conditions.

What is the purpose of the CL auto-discharge feature in the XC6220B series?

The CL auto-discharge feature allows the output capacitor to be quickly discharged through an internal N-channel transistor when the CE pin is pulled low. This ensures the output voltage returns to the VSS level rapidly after shutdown, which is beneficial for systems requiring fast power cycling.
