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

Verify the specific package variant matches the design requirements, as the PR-G suffix denotes the SOT-89-5 configuration. Confirm that the fixed 5.2V output aligns with the target load voltage needs. Ensure input voltage conditions remain within the specified 1.7V to 10.5V range during operation. Check compatibility with ceramic capacitors for stability and phase compensation as recommended in the datasheet.

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

Select this component when a fixed 5.2V output is required with moderate current demands up to 200mA. The SOT-89-5 package provides a balance of thermal performance and footprint size compared to smaller options. Consider the A-series designation which lacks internal capacitor discharge, requiring external management if rapid voltage decay is needed upon shutdown.

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

This part belongs to the XC6505 series of high-speed LDO regulators designed for low power consumption applications. The series covers various output voltages from 1.5V to 8.0V in 0.1V increments. The XC6505A variant specifically omits the internal CL discharge switch found in the B-series, relying on resistive dividers for output discharge in stand-by mode.

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

Does the XC6505A521PR-G have an internal capacitor discharge function?

No, the XC6505A series does not include an internal N-channel MOSFET for CL discharge. It discharges the output voltage through internal resistors R1 and R2 when the CE pin is pulled low.

What is the maximum input voltage for this regulator?

The maximum operating input voltage is 10.5V. The absolute maximum rating for the input voltage is 12.0V.
