XC6701B992PR-G

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

The XC6701B992PR-G is a positive fixed-output linear voltage regulator manufactured by Torex Semiconductor Ltd. It provides a nominal output voltage of 9.9V with a maximum output current capability exceeding 150mA. The device operates within an input voltage range of 2.0V to 28.0V and features high accuracy of ±2.0%. Key electrical characteristics include a typical supply current of 65µA, a power supply rejection ratio (PSRR) of 50dB at 1kHz, and a dropout voltage of approximately 950mV at 100mA load. It incorporates built-in overcurrent protection and thermal shutdown circuits.

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

• Integrated CE pin enables active-high control for turning the output on or off, allowing the IC to enter a low-power stand-by mode.
• Built-in current limiter and thermal protection circuit safeguard against overload conditions and excessive junction temperatures.
• Internal phase compensation allows stable operation using low ESR ceramic capacitors without requiring external components.

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

Verify that the specific part number XC6701B992PR-G matches the required 9.9V output voltage and SOT-89-5 package configuration. Confirm that the system design accommodates the specified operating temperature range of -40°C to 85°C. Ensure the CE pin is properly biased to avoid undefined states during operation.

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

Select this component when a fixed 9.9V output is required from a high-voltage input source up to 28V. It is suitable for applications needing moderate current drive with integrated protection features. Consider the SOT-89-5 package constraints regarding thermal dissipation and board space requirements for the final design.

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