XC6901D681PR-G

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

The XC6901D681PR-G is a negative voltage CMOS regulator from the XC6901 series, manufactured by Torex Semiconductor. It provides a fixed output of -6.8V with a maximum output current of 200mA. The device operates within an input voltage range of -2.4V to -12.4V (with VCE=3.6V). It features high accuracy of ±1.5% for outputs below -2.0V and ±0.03V for outputs at or above -2.0V. The regulator includes an ON/OFF control function via the CE pin, low power consumption, and built-in protection circuits such as current limit and thermal shutdown.

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

Verify the specific package type SOT-89-5 and the fixed output voltage of -6.8V when ordering. Confirm that the 'D' suffix indicates a maximum operating temperature of 85°C. Ensure the '-G' suffix requirement for RoHS compliance is met. Cross-reference the manufacturer part number XC6901D681PR-G with official distributor catalogs to confirm availability and authenticity before purchase.

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

Select this component for applications requiring a stable negative rail with moderate current demands up to 200mA. The SOT-89-5 package offers a balance of thermal performance and size. Consider the dropout voltage characteristics relative to the minimum input voltage required for the specific load. The active-high CE pin allows for easy system-level power management integration.

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

This part belongs to the XC6901 series of negative voltage regulators. The series is designed for portable electronic devices where low power consumption and small footprint are critical. The 'D' designation specifies the commercial temperature grade, while 'PR-G' identifies the SOT-89-5 package and environmental compliance.

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

Consult the official datasheet for alternative packages like SOT-25 or USP-6C with identical electrical specifications if form factor changes are needed. Verify that any substitute maintains the same -6.8V output and 200mA current rating.
