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

Verify that the specific part number XC6210B20AMR-G matches the required B-series logic (High Active, No Pull-Down) and the 2.0V output designation. Confirm the MR suffix corresponds to the SOT-25 package type. Ensure compliance with EU RoHS standards as indicated by the -G suffix.

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

Select this component when a fixed 2.0V output is required with high-speed transient response capabilities. The B-type configuration necessitates driving the CE pin with a defined High or Low signal, as it lacks internal pull-down resistance. Ensure the application load does not exceed the 700mA limit and verify thermal dissipation requirements for the SOT-25 package.

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 is designed for portable devices requiring efficient power management. The 'B' designator indicates a specific control logic variant where the Enable pin is active-high but does not contain an internal pull-down resistor.

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

Substitutes must match the 2.0V fixed output, SOT-25 package, and B-series CE logic. Verify that alternative parts support the same 700mA output current and 60dB ripple rejection specifications.

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

How does the CE pin function on the XC6210B series?

The CE pin is active-high. For the B-series, there is no internal pull-down resistor; therefore, the pin must be driven by a valid High or Low signal to prevent undefined states.

What protection features are included in this regulator?

The IC includes a built-in current limiter with a foldback circuit and short-circuit protection to safeguard the output pin and regulate current flow during overload conditions.
