XC6701D902PR-G

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

The XC6701D902PR-G is a fixed-output positive voltage regulator IC manufactured by Torex Semiconductor using CMOS process technology. It provides a nominal output voltage of 9 V with an accuracy of ±2.0%. The device supports a maximum output current exceeding 150 mA and operates within an input voltage range of 2.0 V to 28.0 V. Key electrical characteristics include a typical supply current of 60 μA, a power supply rejection ratio of 50 dB at 1 kHz, and a dropout voltage of approximately 700 mV at 100 mA load. The component is housed in a SOT-89 package and is rated for an operating ambient temperature range from -40°C to +85°C.

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

• Integrated Chip Enable (CE) function allows the device to enter a low-power standby mode with significantly reduced current consumption when the output is turned off.
• Built-in over-current protection circuit limits output current during short-circuit conditions, while thermal shutdown circuitry protects against excessive junction temperatures.
• Internal phase compensation enables stable operation with low ESR ceramic capacitors without requiring external components for frequency compensation.

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

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

Verify that the specific part number XC6701D902PR-G corresponds to the D-series variant which lacks the Chip Enable pin functionality, despite the PR suffix typically indicating a package type associated with CE-enabled variants in other series members. Confirm the package designation matches the required PCB footprint and ensure the ordering suffix aligns with RoHS compliance requirements specified by the manufacturer.

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

Select this component when a fixed 9 V rail is required from a supply voltage up to 28 V. The D-series designation indicates the absence of a control pin, making it suitable for always-on applications where software or hardware gating is not needed. Ensure the input voltage remains above 2.0 V for proper regulation and verify that the thermal dissipation capabilities of the SOT-89 package are sufficient for the expected load current and ambient temperature conditions.

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

This device belongs to the XC6701 series of high-speed voltage regulators designed for portable electronics and automotive applications. The series utilizes laser trimming to set precise output voltages in 0.1 V increments across a wide range. The D-series specifically denotes a fixed-output version without a Chip Enable function, operating within a standard industrial temperature range of -40°C to +85°C.
