XC6220A231MR-G

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

The XC6220A231MR-G is a CMOS low dropout regulator from Torex Semiconductor, packaged in SOT-25-5. It provides a fixed output voltage of 2.3V with a maximum continuous output current of 1A. The device operates within an input voltage range of 1.6V to 6.0V and features Green Operation technology for automatic switching between high-speed and power-save modes. Key electrical parameters include a typical supply current of 50μA in high-speed mode and 8μA in power-save mode. It includes built-in overcurrent protection, thermal shutdown, and inrush current prevention circuits.

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

Verify the specific ordering suffix MR-G confirms the SOT-25 package and standard reel quantity. Confirm that the 'A' type designation indicates the absence of a CE pull-down resistor and CL auto-discharge feature, which differs from B, C, or D types. Ensure compatibility with system requirements regarding the open-state behavior of the CE pin for this semi-custom variant.

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

Select this component when a fixed 2.3V output is required with high current capability up to 1A. The A-type configuration is suitable for designs where external control of the enable pin does not require an internal pull-down resistor. Consider the thermal dissipation capabilities of the SOT-25 package under expected load conditions and ambient temperatures.

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

This part belongs to the XC6220 series of 1A LDO regulators known for high precision and low noise. The series utilizes laser trimming for accurate output voltage selection in 0.05V increments. The XC6220A variant represents a semi-custom option lacking the CL discharge and CE pull-down resistor found in other series members.

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

Direct substitutes within the same series include XC6220B231MR-G (with CL discharge), XC6220C231MR-G (with CE pull-down), and XC6220D231MR-G (with both). Cross-series replacements may require verification of package dimensions and electrical characteristics.
