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

Verify the specific ordering suffix DR-G confirms the USP-6B package format and Halogen-free compliance. Ensure the B-series designation matches the requirement for High Active CE control without an internal pull-down resistor. Confirm that the 442 code corresponds to the required 4.4V output voltage setting before finalizing procurement.

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

Select this component when a fixed 4.4V rail is needed with high current capability up to 700mA. The B-type configuration requires an active High signal on the CE pin to enable regulation; ensure the control logic can drive this state directly. Verify that the application environment stays within the -40°C to +85°C operating temperature range for optimal performance.

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 process technology. The series offers selectable output voltages in 0.05V increments. The XC6210B variant specifically denotes a High Active Enable pin configuration without an internal pull-down resistor, distinguishing it from A, C, and D series options.
