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

Verify the specific ordering suffix PR-G confirms the SOT-89-5 package format and Halogen/Antimony-free compliance status. Ensure the design accounts for the CE pin's High Active logic with an internal pull-down resistor to prevent undefined states when the control signal is open. Confirm thermal dissipation requirements align with the specified power ratings for the selected PCB mounting conditions.

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

Select this part for applications requiring a fixed 2.5 V rail with high current capability up to 700 mA. The A-type designation indicates High Active CE logic with a pull-down resistor, suitable for systems where the enable signal defaults to inactive or requires explicit high-level activation. Verify that the required output capacitance meets the minimum specifications for stability with low ESR ceramic capacitors across the intended load current range.

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

This component belongs to the XC6210 series of high current, high speed LDO regulators manufactured by Torex Semiconductor. The series utilizes a CMOS process to achieve low power consumption while maintaining high output current capabilities. The XC6210A variant specifically denotes High Active CE control with an internal pull-down resistor, distinguishing it from B, C, and D types which vary in active logic levels and pull-up/pull-down configurations.

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

Substitutes must match the SOT-89-5 package, 2.5 V fixed output, and >700 mA current rating. Verify compatibility with High Active CE logic featuring an internal pull-down resistor. Ensure the replacement supports the same input voltage range (1.5V-6.0V) and operating temperature range (-40°C to +85°C).

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

How does the CE pin function on the XC6210A series?

The XC6210A series features a CE pin that is High Active with an internal pull-down resistor. The regulator turns ON when the CE pin voltage is high (VIN level) and enters stand-by mode when the CE pin is low (VSS level).

What type of output capacitors are recommended for stability?

The XC6210 series is compatible with low ESR ceramic capacitors. For a 2.5 V output, a minimum output capacitor (CL) of 1.0 μF is recommended to ensure stability due to the built-in phase compensation circuit.

What protection features are included in the IC?

The IC includes a built-in current limiter circuit and a foldback circuit. These operate together to limit output current and protect the output pin from short circuits, reducing output voltage and current further if the limit is reached.
