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

Select this component when designing circuits requiring a precise 1.3V rail with minimal quiescent current draw. The SOT-25 package offers a compact footprint suitable for space-constrained applications. Verify that the input voltage remains within the 1.4V to 6.0V range and that load requirements do not exceed the 150mA limit under all operating conditions.

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

This device belongs to the XC6504 series of low-dropout regulators designed for high accuracy and low power usage. The series utilizes laser trimming technology to set output voltages in 0.1V increments. Type A variants include a current limiter and CL auto-discharge feature, distinguishing them from other series configurations.

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

Consult official Torex Semiconductor documentation for confirmed substitute part numbers. Do not assume cross-compatibility with other LDO families without verifying electrical parameters and pin configurations.

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

Does the XC6504A131MR-G require an output capacitor for stability?

No, the IC features a built-in phase compensation circuit that allows for stable operation without an output capacitor (CL) or with low ESR ceramic capacitors.

How does the CE pin function affect the output voltage?

When the CE pin is at a low level, the output is pulled down to the VSS level via an internal discharge resistance, effectively shutting down the regulator and discharging any stored charge on the output line.
