XC6504A3917R-G

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

The XC6504A3917R-G is a fixed-output CMOS voltage regulator from the Torex XC6504 series, providing a nominal output of 3.9V with an accuracy of ±1%. It operates within an input voltage range of 1.4V to 6.0V and delivers up to 150mA of output current while maintaining an ultra-low supply current of 0.6μA at no load. The device features a maximum dropout voltage of 0.51V at 50mA and includes built-in over-current protection. It is housed in the compact USPN-4B02 package (0.75 x 0.95mm) and supports capacitor-less stable operation.

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

Verify the specific part number XC6504A3917R-G against official Torex Semiconductor documentation to confirm the 3.9V output voltage designation and USPN-4B02 packaging. Ensure compliance with RoHS standards and check that the ordering suffix matches the required reel quantity and environmental specifications.

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

Select this component when a fixed 3.9V rail is required with minimal board space constraints due to the small USPN-4B02 footprint. It is suitable for low-power designs where standby current must be minimized. Verify that the input voltage remains above the minimum operating threshold and consider thermal dissipation limits if high load currents are sustained.

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

This part belongs to the XC6504 series of low-dropout regulators designed for mobile and wireless applications.
