XC6223T141MR-G

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

The XC6223T141MR-G is a high-speed LDO voltage regulator from Torex Semiconductor, featuring built-in inrush current protection and an active-high CE control pin with internal pull-down. It delivers a fixed 1.4V output at up to 300mA within a 1.6V to 5.5V input range. The device operates across -40°C to 105°C, offering 80dB ripple rejection and low standby current of 0.01μA. Packaged in SOT-25-5 (MR-G), it includes thermal shutdown and short-circuit protection for reliable portable electronics.

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

• Built-in inrush current protection circuit limits startup surge current.
• Active-high CE function with internal pull-down resistor ensures defined off-state.
• Integrated auto-discharge switch rapidly drains output capacitor charge upon shutdown.
• Supports stable operation using low ESR ceramic capacitors.

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

• Smart phones / Mobile phones
• Portable game consoles
• Wireless LAN modules
• Bluetooth devices

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

Verify the specific suffix MR-G corresponds to the SOT-25 package and 3000pcs/reel quantity. Confirm the 'T' designator indicates compliance with the extended operating temperature range up to 105°C. Ensure the ordering code matches the required 1.4V output voltage and ±1% accuracy specification before finalizing procurement.

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

Select this component when a fixed 1.4V rail is required with minimal quiescent current. The SOT-25 package suits space-constrained designs. Verify that the application load does not exceed the 300mA maximum output current. Consider the internal pull-down on the CE pin if no external control signal is present during power-up.

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

This part belongs to the XC6223 series of high-speed LDO regulators designed for portable consumer electronics. The series emphasizes low noise, high ripple rejection, and compact packaging options including USPQ-4B03, USP-4, SSOT-24, and SOT-89-5. The XC6223T variant specifically extends the operating temperature range to 105°C compared to older A-H types.

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

XC6223H141MR-G: Similar specifications but limited to 85°C operating temperature range. XC6223F141MR-G: Includes inrush protection but lacks the internal CE pull-down resistor.
