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

Verify the specific suffix MR-G corresponds to the SOT-25 package configuration required for your design. Confirm that the 'T' designation indicates compliance with the extended operating temperature range up to 105°C. Ensure the CE pin logic requirements match your system's control signals, as this variant includes internal pull-down resistors. Cross-reference the datasheet for absolute maximum ratings to prevent overstress during integration.

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

Select this component when a fixed 3.6V rail is needed with minimal quiescent current consumption. The SOT-25 package offers a compact footprint suitable for space-constrained portable electronics. The inclusion of inrush current protection makes it suitable for applications sensitive to power-up transients. Verify that the input voltage remains above the minimum threshold plus the dropout voltage under all load conditions.

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

This part belongs to the XC6223 series of high-speed LDO regulators. The series is characterized by low noise, high ripple rejection, and comprehensive protection features. The 'T' in the model number identifies it as a version with an extended operating temperature range of -40°C to +105°C, distinguishing it from older variants limited to 85°C.

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

What is the function of the CE pin in the XC6223T361MR-G?

The CE pin acts as an ON/OFF control input. A high-level signal enables operation, while a low-level signal disables the regulator and activates the internal discharge switch to quickly lower the output voltage.

Does this regulator support ceramic output capacitors?

Yes, the XC6223 series is designed to operate stably with low ESR ceramic capacitors, typically requiring 1.0μF or larger on both the input and output pins.
