XC6501D49AGR-G

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

The XC6501D49AGR-G is a high-speed, low-noise CMOS LDO regulator from Torex Semiconductor. It provides a fixed output voltage of 4.9V 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. It includes a CE pin for standby control, reducing supply current to less than 0.1μA. The package is USP-4, and it supports an operating temperature range of -40℃ to 85℃.

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

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

Verify that the specific part number XC6501D49AGR-G matches the required 4.9V output voltage and USP-4 package configuration. Confirm compliance with EU RoHS standards and lead-free requirements as indicated by the suffix. Ensure design accounts for the internal auto-discharge feature present in the D-series type when implementing power-down states.

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

Select this component for applications requiring stable regulation without external output capacitors to save board space. The D-series designation indicates the inclusion of both a CE pull-down resistor and the CL auto-discharge switch, which aids in faster discharge times compared to other series variants. Verify that the input voltage remains within the 1.4V to 6.0V range for proper operation.

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

This component belongs to the XC6501 series of high-speed LDO regulators designed for portable electronic devices. The series utilizes CMOS technology to achieve low noise and high speed response. The 'D' in the model name specifies the functional variant with CE pull-down and auto-discharge capabilities, while 'GR-G' denotes the USP-4 package and environmental compliance.

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

Other XC6501 series variants such as XC6501A, B, or C types may serve as functional replacements if the specific auto-discharge or pull-down features are not critical. Ensure the replacement part maintains the same 4.9V output voltage and USP-4 package footprint for direct compatibility.
