XC6701B902PR-G

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

The XC6701B902PR-G is a positive fixed-output LDO voltage regulator from Torex Semiconductor, manufactured using CMOS process. It provides a nominal output voltage of 9V with ±2.0% accuracy and supports a maximum output current exceeding 150mA. The device operates within an input voltage range of 2.0V to 28.0V and features a typical dropout voltage of 300mV at 20mA. It includes built-in overcurrent protection and thermal shutdown circuits. The IC consumes low power with a supply current of approximately 60μA and offers high ripple rejection of 50dB at 1kHz. It is housed in a SOT-89-5 package and functions reliably across an ambient temperature range of -40°C to +85°C.

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

Verify the specific ordering suffix PR-G corresponds to the SOT-89-5 package configuration. Confirm that the CE pin is properly biased to either VIN or VSS to prevent undefined operational states. Ensure compliance with RoHS and REACH standards as indicated by the -G suffix. Check absolute maximum ratings against system stress conditions before integration.

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

Select this component when a fixed 9V output is required from inputs up to 28V. The SOT-89-5 package suits applications needing moderate heat dissipation. Verify that the input voltage remains above the minimum threshold of 2.0V for proper regulation. Consider the thermal performance under maximum load conditions relative to the PCB layout.

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

This part belongs to the XC6701 series of 28V operation high-speed voltage regulators. The 'B' designation indicates a fixed output voltage variant with active-high enable functionality, rated for an operating temperature range of -40°C to +85°C. The series utilizes laser trimming technology to set precise output voltages in 0.1V increments.

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

Other variants within the XC6701 series may serve as substitutes if different output voltages or packages are acceptable. Ensure any replacement maintains the same enable logic and thermal characteristics. Cross-reference datasheets for absolute maximum ratings and electrical performance to guarantee compatibility.
