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

Verify the specific package type SOT-25 and the A-series control logic (CE high active, no pull-down, no auto-discharge) against system requirements. Confirm that the fixed 2.0V output aligns with the target circuit design. Ensure input voltage remains within the 1.4V to 6.0V operational range to maintain regulation and prevent damage.

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

Select this component when a compact, low-noise linear regulator is needed for battery-powered applications. The absence of an external output capacitor requirement simplifies PCB layout and reduces component count. The low quiescent current makes it suitable for portable devices where power efficiency in both active and stand-by modes is critical.

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

Does the XC6501A201MR-G require an external output capacitor?

No, the device incorporates internal phase compensation, allowing it to operate stably without an external load capacitor.

What is the function of the CE pin on this regulator?

The CE (Chip Enable) pin controls the ON/OFF state. Applying a high level turns the regulator on, while a low level activates stand-by mode, reducing supply current to less than 0.1μA.
