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

Verify the complete part number XC6220D36BPR-G against official Torex Semiconductor documentation to confirm the specific 3.6V output voltage and D-type CE pull-down resistor configuration. Ensure compatibility with required ceramic output capacitors for stable phase compensation as specified in the datasheet application notes.

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

Select this component for applications requiring a fixed 3.6V supply with up to 1A load capability. The D-series designation indicates the presence of a CE pull-down resistor and CL auto-discharge feature, which aids in system power management. Verify that the input voltage remains within the 1.6V to 6.0V range for proper regulation.

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

This device belongs to the XC6220 series of 1A LDO regulators known for ultra-low dropout voltage and high accuracy. The series utilizes laser trimming for precise output voltage selection in 0.05V increments. The 'D' suffix denotes a semi-custom variant with both CE pull-down resistance and output capacitor discharge functionality integrated internally.

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

Compatible substitutes within the same family include other XC6220 variants with different output voltages or package types, such as XC6220C36BPR-G (without CL discharge) or XC6220D36MR-G (SOT-25 package). Verify pinout and functional differences before substitution.

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

What is the function of the 'D' type designation in the XC6220 series?

The 'D' type designation indicates that the IC includes both a CE pull-down resistor and a CL auto-discharge N-channel transistor switch, allowing for faster output voltage decay when the enable pin is deactivated.

How does the Green Operation function work?

Green Operation automatically switches the regulator between High Speed (HS) mode for heavy loads and Power Save (PS) mode for light loads, significantly reducing supply current during low-power conditions to extend battery life.
