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

Verify the specific suffix MR-G confirms the SOT-25 package format and lead-free compliance. Ensure the B designation matches the required High Active enable logic without internal pull-down resistors. Confirm RoHS3 status aligns with environmental requirements for the target assembly process.

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

Select this component when a precise 4.9V rail is required with moderate current demands up to 700mA. The B-type configuration necessitates external control circuitry to drive the CE pin high for activation, as it lacks an internal pull-down resistor. Consider thermal dissipation limits on the PCB layout due to the small surface mount footprint.

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

This part belongs to the XC6210 series of high-current, high-speed LDO regulators fabricated using CMOS processes. The series offers selectable output voltages in increments across a wide range. The XC6210B variant specifically defines the enable pin behavior as active-high without internal pull-down resistance.

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

What is the minimum recommended output capacitor value for this voltage?

For an output voltage of 4.9V, which falls within the 1.80V to 5.00V range, a minimum output capacitor of 1.0µF is required.

How does the CE pin operate for the B-series type?

The B-series type is High Active with no internal pull-down resistor. The IC activates when the CE pin is driven high and enters standby when driven low; leaving the pin open results in an undefined state.
