XC6501D41AGR-G

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

The XC6501D41AGR-G is a high-speed, low-noise CMOS LDO regulator from Torex Semiconductor. It provides a fixed output voltage of 4.1V with a maximum output current of 200mA. The device operates within an input voltage range of 1.4V to 6.0V and features internal phase compensation, allowing for stable operation without an external load capacitor (CL). It includes a CE pin for standby control, reducing supply current to less than 0.1μA. The part is housed in a USP-4 package.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Internal phase compensation enables stable regulation without requiring an external output capacitor.
• CE function allows entry into standby mode with ultra-low current consumption via low-level signal input.
• Built-in CL auto-discharge switch rapidly discharges stored charge in the output capacitor during shutdown.
• Fold-back current limit circuit provides short-circuit protection and limits output current.

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

Verify the specific ordering suffix GR-G corresponds to the USP-4 package format and reel quantity as defined in the official datasheet. Confirm that the D series designation matches the required CE pull-down and CL discharge functionality for the target application design. Ensure compliance with RoHS and halogen-free requirements specified by the -G suffix before finalizing procurement orders.

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

Select this component when a fixed 4.1V output is required from a single-channel LDO. The D series variant is appropriate if automatic output discharge upon shutdown is necessary. Consider the USP-4 package dimensions for PCB layout constraints. Verify that the input voltage remains within the 1.4V to 6.0V operational range under all expected load 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 utilizes CMOS technology to achieve low power consumption and high speed response. The XC6501D indicates a specific configuration with CE pull-down and CL discharge capabilities, distinguishing it from A, B, and C series variants which lack one or both of these features.

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

Other XC6501 series parts with different output voltages or package types may serve as functional substitutes if electrical parameters align. Verify pin compatibility and thermal dissipation characteristics when replacing with alternative packages such as SSOT-24 or SOT-25.

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

What is the function of the CE pin in the XC6501D series?

The CE pin controls the ON/OFF state. A high level turns the regulator on, while a low level activates standby mode. In the D series, a low level also triggers the internal auto-discharge switch to drain the output capacitor.

Does the XC6501D41AGR-G require an output capacitor?

No, the device features internal phase compensation, allowing it to operate stably without an external load capacitor (CL).
