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

Verify that the ordering suffix NR-G corresponds to the SSOT-24 package as specified in the official datasheet. Confirm that the designator C indicates a High Active CE pin with a pull-down resistor but without the CL auto-discharge function. Ensure compatibility with the required 4.1V output specification before procurement.

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

Select this component when a fixed 4.1V output is required with minimal external component count due to the lack of output capacitor requirement. The SSOT-24 package offers a compact footprint suitable for space-constrained portable designs. The presence of the CE pin with pull-down ensures defined logic states during startup or fault conditions.

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

This part belongs to the XC6501 series of 200mA high-speed LDO regulators. The series is characterized by its ability to operate stably without load capacitors, a feature achieved through internal phase compensation. The C designation specifically denotes the control logic variant with a CE pull-down resistor, distinguishing it from variants with or without discharge functions.
