XC6806C405DR-G

Battery Chargers Overview

The XC6806C405DR-G is a fixed-output low-dropout (LDO) voltage regulator manufactured by Torex Semiconductor. It provides a stable output voltage of 4.0V with a maximum output current capability of 150mA. The device features an internal P-channel MOSFET pass element, enabling operation with a very low input-to-output differential voltage. Key electrical specifications include a typical dropout voltage of 200mV at 150mA load and a quiescent current of approximately 3µA. It incorporates built-in protection circuits for overcurrent limiting and thermal shutdown to ensure reliable operation under fault conditions.

Battery Chargers Feature Summary

• Integrated P-channel MOSFET pass transistor for high efficiency and low dropout performance
• Built-in overcurrent protection circuit to limit output current during short-circuit or overload events
• Thermal shutdown circuit activates to protect the device from damage due to excessive junction temperature

Battery Chargers Applications

• Portable battery-powered electronic devices requiring efficient power management
• Embedded systems needing stable low-noise voltage regulation
• Consumer electronics utilizing CMOS logic circuits

Battery Chargers Procurement Notes

Verify the specific suffix DR-G against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the ordering code matches the required output voltage tolerance and operating temperature range defined in the product documentation before procurement.

Battery Chargers Selection Notes

Select this component when a fixed 4.0V output is required with minimal external components. Consider its low quiescent current for battery-operated applications. Verify that the input voltage remains within the specified absolute maximum ratings and that the thermal environment allows for adequate heat dissipation given the 150mA current capability.

Battery Chargers Part Context

This part belongs to the XC6806 series of LDO regulators designed for low-power applications. The series offers various fixed output voltages and utilizes a compact SOT-25-3 package. It is engineered to replace older linear regulators while providing improved efficiency and lower standby current consumption in portable equipment.

Battery Chargers Replacement Considerations

Check for direct pin-compatible alternatives within the same series offering different output voltages. Verify if other manufacturers provide equivalent P-channel LDOs with matching current ratings and protection features. Ensure any substitute maintains the same package outline and electrical characteristics.
