XC6222A381MR-G

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

The XC6222A381MR-G is a fixed-output low-dropout regulator manufactured by Torex Semiconductor. It provides a stable 3.8 V output with a maximum continuous current of 700 mA. The device operates within an input voltage range of 1.7 V to 6 V and maintains a typical power supply rejection ratio of 65 dB at 1 kHz. Quiescent current is specified at 100 uA, ensuring efficient operation in battery-powered applications. The unit features a dropout voltage of 120 mV at rated load and includes internal protection against overcurrent and thermal overload. It is housed in a compact SOT-25-5 surface-mount package suitable for space-constrained designs.

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

Verify the specific suffix MR-G corresponds to the SOT-25-5 package and reel packaging format required for your assembly process. Confirm that the 3.8 V fixed output matches your system design specifications before ordering. Ensure compatibility with the manufacturer's RoHS compliance documentation. Cross-reference the part number with official distributor catalogs to validate availability and lead times for production quantities.

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

Select this component when a fixed 3.8 V rail is needed with high current capability up to 700 mA. The SOT-25-5 package offers a balance between thermal performance and board space efficiency. Consider the 100 uA quiescent current if battery longevity is critical. Verify that the input voltage remains above 1.7 V and below 6 V under all operating conditions to ensure proper regulation and protection functionality.

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

This part belongs to the XC6222 series of high-speed LDO regulators from Torex Semiconductor. The series is characterized by its ability to drive heavy loads while maintaining stability with small output capacitors. The A-series designation typically indicates specific output voltage tolerances and package options within the broader product line. These regulators are designed for applications demanding fast transient response and low noise performance.

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

Check for direct substitutes such as XC6222A381PR-G if a different package like SOT-89-5 is preferred. Verify pinout compatibility and thermal dissipation requirements when switching packages. Ensure that any replacement maintains the same 3.8 V output and 700 mA current rating. Consult official cross-reference lists for validated alternatives.
