XC6501C441GR-G

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

The XC6501C441GR-G is a high-speed, low-noise CMOS LDO regulator manufactured by Torex Semiconductor. It provides a fixed output voltage of 4.4V 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). Key electrical parameters include a typical dropout voltage of 150mV at 100mA, a supply current of 13μA, and a ripple rejection ratio of 50dB at 1kHz. The part is housed in a USP-4 package and supports an operating ambient temperature range from -40°C to 85°C.

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

• Internal phase compensation enables stable regulation without requiring an external output capacitor.
• Built-in CL auto-discharge function rapidly pulls the output voltage to ground when the CE pin is set to low level.
• Fold-back current limit circuit provides short-circuit protection and limits output current during overload conditions.

• Bluetooth devices
• Digital-TV tuners

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

Verify that the specific ordering suffix matches the required package type and functional variant. Confirm that the 'C' designation corresponds to a High Active CE pin with an internal pull-down resistor. Ensure the '-GR-G' suffix aligns with the USP-4 package format and RoHS compliance requirements for the target manufacturing process.

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

Select this component when a fixed 4.4V output is required with a maximum load of 200mA. The internal phase compensation makes it suitable for designs aiming to minimize external component count by eliminating the need for a load capacitor. Verify that the input voltage remains within the 1.4V to 6.0V range and that the thermal dissipation capabilities of the USP-4 package are sufficient for the application's power budget.

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

This part belongs to the XC6501 series of high-speed LDO regulators. The 'C' series variant specifically includes a CE pin with an internal pull-down resistor, ensuring a defined OFF state if the control pin is left open. The 'GR-G' suffix indicates the USP-4 surface mount package and halogen-free/RoHS-compliant construction.

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

XC6501B441GR-G: Similar functionality but lacks the internal CE pull-down resistor found in the C series.

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

Does the XC6501C441GR-G require an external output capacitor?

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

What is the function of the CE pin on the XC6501C series?

The CE pin controls the ON/OFF state of the regulator. On the C series, it is internally pulled down, meaning a low signal turns the device off, while a high signal turns it on.
