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

Verify the specific package type USP-6B and CE logic configuration (High Active, No Pull-down) against system requirements. Confirm compliance with EU RoHS and Halogen/Antimony-free standards indicated by the -G suffix. Ensure proper thermal management due to power dissipation limits in the small outline package.

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

Select this part for applications requiring a fixed 4.8V rail with high current capability. The B-type designation indicates High Active CE control without an internal pull-down resistor, requiring external biasing or connection to VIN/VSS to prevent undefined states. Verify that the required output capacitance meets the minimum values specified for the 4.8V output range to ensure stability.

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

What is the recommended output capacitor value for the XC6210B48ADR-G?

For an output voltage of 4.8V, which falls within the 1.80V to 5.00V range, a minimum output capacitor (CL) of more than 1.0μF is required.

How does the CE pin function for the XC6210B series?

The XC6210B series has a High Active CE pin with no internal pull-down resistor. The IC activates when the CE pin is HIGH (VIN) and enters stand-by when LOW (VSS). An open CE pin results in an undefined state.
