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

Verify the specific package type SOT-25 and the B-series logic configuration (CE High Active, no pull-down) against system requirements. Confirm that the 2.15V output voltage aligns with load specifications. Ensure compliance with RoHS and halogen-free standards indicated by the -G suffix. Check absolute maximum ratings for thermal management during operation.

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

Select this component when a fixed 2.15V output is required with high current drive capabilities. The B-type designation indicates the enable pin requires an external high signal for activation and lacks an internal pull-down resistor, necessitating careful circuit design to prevent undefined states. Consider the 2% accuracy tolerance suitable for general-purpose applications.

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

This part belongs to the XC6210 series of high current, high speed LDO regulators. The series offers various output voltages in 0.05V increments and multiple package options including SOT-25, SOT-89-5, and USP-6B. The B-series specifically denotes a CE pin configuration that is active high without an internal pull-down resistor, distinguishing it from A, C, and D types.

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

XC6210B21AMR-G is a direct replacement for other XC6210B21 variants with different packaging if pin compatibility allows. Verify CE pin logic compatibility when substituting with A, C, or D series parts due to differing internal pull-up/down resistor configurations.
