XC6501C12AGR-G

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

The XC6501C12AGR-G is a high-speed, low-noise CMOS LDO regulator from Torex Semiconductor. It provides a fixed output voltage of 1.2V with a maximum output current of 200mA. The device operates within an input voltage range of 1.4V to 6.0V and achieves stable regulation without requiring an external load capacitor due to internal phase compensation. Key electrical characteristics include a typical supply current of 13μA, ripple rejection of 50dB at 1kHz, and a dropout voltage of 440mV at 100mA. It features CE control for stand-by mode with less than 0.1μA consumption and includes current limit and short-circuit protection.

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

Verify the specific ordering suffix GR-G confirms the USP-4 package and reel quantity. Confirm the C designator indicates CE High Active with CE Pull-down functionality. Ensure the 12 designator corresponds to the 1.2V nominal output voltage. Check RoHS compliance status as indicated by the -G suffix in official documentation.

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

Select this component when a fixed 1.2V output is required with minimal quiescent current. The USP-4 package suits space-constrained designs. The C-type variant is appropriate if a pull-down resistor on the CE pin is needed to prevent undefined states. Verify that the 200mA load requirement does not exceed the thermal limits of the chosen PCB layout.

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. The XC6501C12AGR-G specifically utilizes the USP-4 package and offers a 1.2V fixed output with CE control featuring a pull-down resistor.

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

Does the XC6501C12AGR-G require an external output capacitor?

No, the device incorporates internal phase compensation, allowing it to provide stable output voltages 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. A high signal turns the regulator on, while a low signal activates stand-by mode. The C type includes an internal pull-down resistor to ensure the device remains off if the pin is left open.
