XC6223T211MR-G

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

The XC6223T211MR-G is a fixed positive LDO voltage regulator from Torex Semiconductor, providing a precise 2.1V output with a maximum load current of 300mA. It operates within an input voltage range of 1.6V to 5.5V and features a typical dropout voltage of 200mV at full load. The device maintains low quiescent current of 100µA and offers high power supply rejection ratio (PSRR) of 80dB. It includes built-in inrush current protection, thermal shutdown, and current limit circuits. The component is housed in a compact SOT-25 package and supports operation temperatures from -40°C to +105°C.

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

Verify the specific suffix 'MR-G' matches the required tape and reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the ordering code aligns with the exact 2.1V fixed output variant. Cross-reference the manufacturer part number against authorized distributor catalogs to avoid counterfeit components. Validate that the SOT-25 package dimensions meet your PCB footprint requirements before finalizing procurement.

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

Select this regulator when a fixed 2.1V output is required with minimal external component usage. Consider the 300mA current capability for moderate load applications. Evaluate the 100µA quiescent current for battery life optimization. Check if the 80dB PSRR meets your noise sensitivity requirements. Verify that the input voltage range accommodates your source supply variations under all operating conditions.
