XC6501B2417R-G

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

The XC6501B2417R-G is a fixed-output CMOS LDO regulator from Torex Semiconductor, providing a nominal output voltage of 2.4V with a tolerance of ±1%. It supports a maximum output current of 200mA and operates within an input voltage range of 1.4V to 6.0V. The device features internal phase compensation, allowing stable operation without an external load capacitor. It includes a CE pin for active-high control, enabling stand-by current consumption below 0.1μA. The USPN-4 package variant offers a typical dropout voltage of 130mV at 100mA load.

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

Verify the specific ordering suffix '7R-G' corresponds to the USPN-4 package and 5,000-piece reel quantity. Confirm that the 'B' series designation matches requirements for active-high CE control and integrated auto-discharge functionality. Ensure the 2.4V output voltage aligns with target circuit specifications before finalizing procurement.

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

Select this component for applications requiring high-speed transient response and low quiescent current in space-constrained designs. The USPN-4 package is suitable for compact PCB layouts. Verify that the input voltage remains above the minimum operating threshold of 1.4V and consider the thermal dissipation limits inherent to the small outline package during continuous operation.

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

Does the XC6501B2417R-G require an external output capacitor?

No, the device utilizes internal phase compensation to ensure stable operation without an external load capacitor.

How does the CE pin function on this specific model?

The CE pin is active-high; applying a high-level signal turns the regulator on, while a low-level signal activates stand-by mode and engages the auto-discharge function.
