XC6210D45ADR-G

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

The XC6210D45ADR-G is a positive fixed-output low dropout regulator from the XC6210 series, manufactured by Torex Semiconductor. It provides a nominal output voltage of 4.5V with a maximum output current exceeding 700mA. The device operates within an input voltage range of 1.5V to 6.0V and features a typical dropout voltage of 50mV at 100mA load. It incorporates a CE pin for standby control, which is active-low without an internal pull-up resistor. The unit utilizes a USP-6B package (1.8x2mm) and maintains operation across an ambient temperature range of -40°C to +85°C.

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

Verify the specific suffix 'DR-G' corresponds to the USP-6B package and RoHS compliance status. Confirm that the 'D' designation indicates a Low Active CE pin configuration without an internal pull-up resistor, requiring external circuitry or direct logic drive for proper enable/disable functionality. Ensure the ordering code matches the required 4.5V output specification.

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

Select this component when a fixed 4.5V rail is required with high current demand up to 700mA. The D-series variant is suitable for systems where the control signal logic is inverted (active-low). Consider the thermal dissipation capabilities of the USP-6B package relative to the PCB layout, as power handling depends significantly on copper area and board standards.

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

This part belongs to the XC6210 series of high-speed, high-current LDO regulators fabricated using CMOS process technology. The series offers selectable output voltages in 0.05V increments from 0.80V to 5.00V. The D-type specifically denotes a Low Active CE pin configuration, distinguishing it from A, B, and C types which vary in active level and internal pull-resistor presence.

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

Direct substitutes within the same family include other XC6210 variants with different output voltages or packages, such as XC6210DxxMR-G (SOT-25) or XC6210DxxPR-G (SOT-89-5), provided the output voltage and CE logic requirements are met. Cross-brand replacements require matching electrical parameters including dropout voltage, current limit, and PSRR.
