XC6501D3720R-G

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

The XC6501D3720R-G is a high-speed, low-noise CMOS LDO regulator from Torex Semiconductor. It provides a fixed output voltage of 3.7V 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 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 includes CE control functionality with a pull-down resistor and an auto-discharge circuit for the output capacitor.

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

• Internal phase compensation enables stable regulation without requiring an external output capacitor.
• CE pin control allows switching between active operation and stand-by mode with ultra-low current consumption.
• Built-in CL auto-discharge function rapidly pulls the output voltage to ground when disabled.
• Fold-back current limit circuit provides protection against short circuits and overcurrent conditions.

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

Verify the package type USP-4 and the specific ordering suffix -G which indicates Halogen and Antimony free compliance. Confirm that the D-series designation matches requirements for CE pull-down and CL discharge functions. Ensure the fixed 3.7V output aligns with system design needs before procurement.

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

Select this component for applications requiring a compact solution without external output capacitors. The D-series variant is suitable where automatic output discharge upon shutdown is required. Consider the 200mA current capability and 1.4V minimum input voltage for battery-powered systems.

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 low power consumption and high speed response. The XC6501D variant specifically integrates a CE pull-down resistor and an N-channel transistor for CL auto-discharge, distinguishing it from other series types like A or C.

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

Other parts in the XC6501 series may serve as alternatives if different output voltages or package types are acceptable. Verify that any substitute maintains the same CE logic level and discharge functionality if those features are critical to the design.
