XC6223T281NR-G

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

The XC6223T281NR-G is a high-speed low-dropout (LDO) voltage regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 2.8 V with a maximum output current of 300 mA. The device operates within an input voltage range of 1.6 V to 5.5 V and features a typical dropout voltage of 240 mV at full load. Quiescent current is maintained at 100 μA, while standby current drops to 0.1 μA when the Control/Enable (CE) pin is deactivated. The regulator offers a ripple rejection ratio of 80 dB at 1 kHz and maintains voltage regulation accuracy within ±1%. It supports stable operation using low ESR ceramic capacitors and includes integrated protection circuits for overcurrent, short-circuit, and thermal shutdown.

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

Verify the specific suffix 'NR-G' against the official Torex datasheet to confirm package type and tape-and-reel specifications. Ensure the selected variant matches the required operating temperature range and compliance standards. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and avoid counterfeit components. Confirm that the ordering information aligns with the latest product release notes.

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

Select this component for applications requiring a fixed 2.8 V supply from a single-cell lithium battery or similar source. The low quiescent current makes it suitable for battery-powered portable electronics where power efficiency is critical. The inclusion of inrush current protection allows direct connection to power sources without external limiting resistors. Verify that the load current does not exceed 300 mA and that the input voltage remains within the specified 1.6 V to 5.5 V range for proper regulation.
