XC6701DC42JR-G

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

The XC6701DC42JR-G is a positive fixed-output voltage regulator from the Torex Semiconductor XC6701 series, manufactured using CMOS process technology. It operates within an input voltage range of 2.0V to 28.0V and provides a fixed output voltage of 4.2V with ±2.0% accuracy. The device supports a maximum output current exceeding 150mA and features low power consumption with a typical supply current of 65μA. It includes built-in overcurrent protection and thermal shutdown circuits for system safety.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Integrated overcurrent protection circuit that activates when output current reaches the limit level.
• Built-in thermal protection circuit that shuts down the driver transistor if junction temperature exceeds the limit.
• Internal phase compensation allows stable operation compatible with low ESR ceramic capacitors.

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

• Car audio systems
• Car navigation systems
• Mobile devices and terminals

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

Verify the specific package type TO-252 and the absence of the Chip Enable (CE) function, as indicated by the 'D' designator in the part number. Confirm the fixed output voltage of 4.2V and ±2.0% accuracy match the application requirements. Ensure the operating ambient temperature range of -40℃ to 85℃ is suitable for the intended environment before finalizing procurement.

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

Select this component for applications requiring a high-voltage input up to 28V and a fixed 4.2V output. The TO-252 package is suitable for higher power dissipation needs compared to smaller packages. Consider the lack of a CE pin for designs where constant operation without external control signals is preferred. Verify that the required output current does not exceed the 150mA limit under the expected input voltage and temperature conditions.

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

This component belongs to the XC6701 series of 28V operation high-speed voltage regulators. The series utilizes CMOS manufacturing processes and offers various output voltages selectable in 0.1V increments via laser trimming. The XC6701D variant specifically denotes a version without a Chip Enable (CE) function and is rated for an operating temperature range of -40℃ to 85℃.
