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

Verify the specific ordering suffix MR-G confirms the SOT-25 package and reel quantity. Confirm the 'B' series designation indicates High Active logic without a pull-down resistor. Ensure the 'A' accuracy code matches the required tolerance for the 4.95V output. Check RoHS compliance status as indicated by the '-G' suffix.

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

Select this component when a fixed 4.95V rail is required with high current capability. The B-series logic requires external drive for the CE pin; ensure the control signal aligns with High Active requirements. Verify that the application load does not exceed the thermal dissipation limits for the SOT-25 package under worst-case input voltage differentials.

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

This part belongs to the XC6210 series of high-current LDO regulators fabricated using CMOS processes. The series is designed for portable devices requiring stable power delivery with low quiescent current. The B-type variant specifically lacks an internal pull-down resistor on the Control Enable pin, distinguishing it from A, C, and D types.

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

What is the logic state for enabling the XC6210B series?

The XC6210B series uses High Active logic, meaning the regulator is enabled when the CE pin is driven High (VIN) and enters standby mode when driven Low (VSS).

Does the XC6210B49AMR-G have an internal pull-down resistor on the CE pin?

No, the B-series designation indicates that there is no internal pull-down resistor on the CE pin. An undefined state may occur if the pin is left open.

What is the output voltage accuracy for the 4.95V setting?

For output voltages between 1.55V and 5.00V, the accuracy is specified as ±2%.
