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

Verify the specific suffix 'NR-G' corresponds to the SSOT-24 package and RoHS compliance status as defined in the official datasheet. Confirm that the 'T' designator indicates the extended operating temperature range up to 105°C. Ensure compatibility with the required input/output capacitor values for stability.

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

Select this component when a fixed 3.7V rail is required with high ripple rejection and fast transient response. The 'T' series variant is suitable for applications requiring operation up to 105°C ambient temperature. Verify that the system input voltage remains within the 1.6V to 5.5V range and that the load current does not exceed 300mA.

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

This part belongs to the XC6223 series of LDO regulators featuring built-in inrush current protection. The series offers various output voltages selectable in 0.05V increments. The 'T' designation specifically denotes the version with an extended operating temperature range compared to the standard 'H' series.

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

Direct substitutes within the same series include XC6223H37BNR-G, noting the difference in maximum operating temperature (85°C vs 105°C). Other variants with different output voltages or package types may require schematic adjustments.

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

What is the function of the CE pin in the XC6223T37BNR-G?

The CE (Chip Enable) pin controls the ON/OFF state. A high-level signal activates the regulator, while a low-level signal enters stand-by mode. This type includes an internal pull-down resistor and an auto-discharge switch for the output capacitor.

How does the inrush current protection work?

During startup, if the output voltage is below approximately 30% of the set value, the inrush current is limited to a typical value of 150mA to prevent excessive surge currents from the input source.
