XC6501D2120R-G

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

The XC6501D2120R-G is a fixed-output CMOS LDO regulator from Torex Semiconductor, providing a nominal output voltage of 2.1V with a maximum continuous current of 200mA. It operates within an input voltage range of 1.4V to 6.0V and features internal phase compensation, allowing stable operation without an external load capacitor. The device includes a CE pin for active-high control, enabling stand-by currents below 0.1μA. It incorporates CL auto-discharge functionality and is housed in a WLP-4-01 package.

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

Verify the specific ordering suffix '20R-G' against official documentation to confirm the WLP-4-01 package type and reel quantity. Ensure the design supports the high-speed transient response characteristics by placing input capacitors close to the IC. Confirm that the application environment remains within the specified operating temperature range.

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

Select this component when a compact footprint is required due to its WLP-4-01 packaging. It is suitable for battery-powered applications requiring low quiescent current and fast response times. The inclusion of the CE pin and auto-discharge feature makes it ideal for systems needing efficient power management and quick state transitions.

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

This part belongs to the XC6501 series of high-speed, low-noise LDO regulators. The series is characterized by its ability to operate stably without external output capacitors. The 'D' designation indicates the presence of both a CE pull-down resistor and the CL auto-discharge function, distinguishing it from other variants in the family.

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

Substitutes must match the 2.1V output, 200mA current rating, and WLP-4-01 package. Verify that any alternative also supports capacitor-less operation and possesses similar CE pin logic and discharge capabilities to maintain system stability.
