XC6223T39BNR-G

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

The XC6223T39BNR-G is a high-speed LDO voltage regulator from Torex Semiconductor. It provides a fixed 3.9V output with a maximum current of 300mA. The device operates within an input voltage range of 1.6V to 5.5V and features a dropout voltage of 200mV at full load. Key electrical characteristics include a supply current of 100μA, standby current of 0.01μA, and ripple rejection of 80dB at 1kHz. It incorporates built-in inrush current protection, thermal shutdown, and short-circuit protection. The component is housed in an SSOT-24 package and supports operation across temperatures from -40°C to 105°C.

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

Verify the specific ordering suffix NR-G corresponds to the SSOT-24 package configuration. Confirm that the 'T' designator indicates compliance with the extended operating temperature range up to 105°C. Ensure the part number matches the required 3.9V output voltage specification before procurement.

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

Select this component when a fixed 3.9V rail is required with moderate current demands up to 300mA. The SSOT-24 package offers a compact footprint suitable for space-constrained portable designs. The inclusion of inrush current protection makes it suitable for systems sensitive to power-up transients.

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

This part belongs to the XC6223 series of high-speed LDO regulators. The series utilizes laser trimming technology to achieve precise output voltages in 0.05V increments. The 'T' prefix denotes a variant with an extended operating temperature range compared to older A-H types.

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

Direct substitutes within the same series include XC6223x39BNR-G variants with different temperature ratings or package options. Verify pin compatibility and thermal performance when replacing with other LDO families.

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

Does the XC6223T39BNR-G support ceramic output capacitors?

Yes, the device is designed to be stable with low ESR ceramic capacitors, typically requiring 1.0μF or larger for phase compensation.

How does the CE pin function operate in this model?

The CE pin is active-high. Inputting a low-level signal places the IC in stand-by mode, activating the internal discharge switch to quickly return VOUT to VSS level.
