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

Verify the specific package type and marking code against the official datasheet before procurement. Confirm that the ordering suffix matches the required reel quantity and environmental compliance standards. Ensure the input voltage requirements align with the system design constraints.

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

Select this part when a fixed 3.8V output is required in space-constrained designs. The USPQ-4B04 package offers thermal advantages over smaller footprints. Verify that the load current does not exceed 150mA and that the dropout voltage characteristics fit the minimum input voltage available in the application.

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

This component belongs to the XC6504 series of low-dropout regulators designed for battery-powered applications. The series covers various fixed output voltages from 1.1V to 5.0V in 0.1V increments. The 'A' designation indicates Type A internal circuitry, which includes a current limiter but lacks a pull-down resistor on the CE pin.

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

Does the XC6504A3819R-G require an output capacitor?

No, the device is designed for stable operation without an output capacitor or with a low ESR ceramic capacitor due to its built-in phase compensation circuit.

What is the function of the CE pin?

The CE pin controls the ON/OFF state of the regulator. A high logic level enables the output, while a low level shuts it down and activates the CL auto-discharge function to rapidly discharge the output capacitor.
