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

Verify the specific suffix 'MR-G' indicates the SOT-25 package format and compliance with RoHS standards including halogen and antimony-free composition. Confirm that the 'B' designation corresponds to High Active logic without a pull-down resistor on the CE pin. Ensure the ordering code matches the required 4.2 V output specification before procurement.

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

Select this component when a fixed 4.2 V output is required with high current capability up to 700 mA. The B-type configuration necessitates external control of the CE pin as it lacks an internal pull-down resistor. Ensure the application utilizes ceramic capacitors meeting the minimum capacitance requirements for the specified output voltage to maintain stability.

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

What is the recommended output capacitor type for the XC6210B422MR-G?

The device is compatible with low ESR ceramic capacitors. For an output voltage of 4.2 V, a minimum capacitance of 1.0 µF is required.

How does the CE pin function operate for the XC6210B series?

The XC6210B series has High Active logic with no internal pull-down resistor. The IC is enabled when the CE pin is at a high level (VIN) and enters standby mode when at a low level (VSS). An open CE pin results in an undefined state.
