XC6501A40B0R-G

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

The XC6501A40B0R-G is a CMOS LDO regulator from Torex Semiconductor, featuring an internal phase compensation circuit that ensures stability without requiring an external load capacitor. It provides a fixed output voltage of 4.0V with ±2% accuracy in the WLP-4-01 package. The device supports a maximum output current of 200mA and operates within an input voltage range of 1.4V to 6.0V. Key electrical characteristics include a typical dropout voltage of 120mV at 100mA, a supply current of 13μA, and a ripple rejection ratio of 50dB at 1kHz. It includes CE control for stand-by mode with less than 0.1μA consumption.

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

Verify the specific ordering suffix '0R-G' corresponds to the WLP-4-01 package type and 5000-piece reel quantity as defined in the official datasheet. Confirm that the 'A' series designation matches the required CE pin logic (High Active) and absence of pull-down resistors. Ensure environmental compliance requirements align with the Halogen-free and RoHS specifications.

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

Select this component when board space is limited by the WLP-4-01 package size. Choose the A-series variant if the design requires High Active CE logic without internal pull-downs. Verify that the 4.0V output meets system requirements and that the 200mA current capacity is sufficient for peak loads.
