XC6220B411PR-G

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

The XC6220B411PR-G is a fixed-output CMOS LDO regulator from the Torex XC6220 series, housed in a SOT-89-5 package. It provides a nominal output voltage of 4.1V with a maximum continuous output current of 1A for voltages between 1.2V and 5.0V. The device operates within an input voltage range of 1.6V to 6.0V and features Green Operation technology that automatically switches between high-speed and power-save modes. Key electrical characteristics include a typical dropout voltage of 85mV at 300mA and 120mV at 1000mA (for VOUT=4.1V), a ripple rejection ratio of 50dB at 1kHz, and a standby current of 0.1μA maximum.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrates Green Operation function to automatically switch between high-speed and power-save modes based on load current levels.
• Features built-in CL auto-discharge circuitry to rapidly discharge output capacitors when the CE pin is pulled low.
• Includes comprehensive protection mechanisms such as over-current limiting, thermal shutdown, and inrush current prevention.
• Utilizes laser trimming technology to achieve high output voltage accuracy across the selectable voltage range.

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

Verify the specific ordering suffix PR-G confirms the SOT-89-5 package type and 1000 pieces per reel quantity. Ensure the B designation matches requirements for no CE pull-down resistor and presence of CL auto-discharge functionality. Confirm RoHS compliance and halogen-free status align with environmental specifications.

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

Select this component when a fixed 4.1V output is required with up to 1A load capability. The B-type variant is suitable for designs needing automatic output capacitor discharge upon shutdown without an external pull-down resistor. Verify input voltage stability remains above the minimum operating threshold to maintain regulation under all expected load conditions.

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

This part belongs to the XC6220 series of 1A LDO regulators featuring Green Operation. The series offers various output voltages in 0.05V increments and multiple package options including SOT-25 and USP-6C. The B-type specifically denotes standard configuration with CL discharge but without a CE pull-down resistor.

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

Direct substitutes within the same series include XC6220B411MR-G (SOT-25-5 package) or XC6220B411ER-G (USP-6C package). Cross-series replacements require verification of output voltage, current rating, and package compatibility.
