The LT1175CQ#TRPBF is a high-performance negative low dropout (LDO) regulator designed and manufactured by Linear Technology, now part of Analog Devices. This regulator offers a robust power management solution for a wide array of applications requiring a stable and efficient negative voltage supply.

Key Features

• Output Voltage: The device provides a fixed output voltage of -5V, making it ideal for precision analog circuits and other voltage-sensitive applications.
• Low Dropout Voltage: With a low dropout voltage of just 500mV at full load, the LT1175 ensures efficient operation even when the input voltage is close to the output voltage, reducing power loss and improving overall system efficiency.
• Adjustable Current Limit: The built-in current limit can be adjusted via an external resistor, providing additional protection for the power supply and the load from excessive current conditions.
• Low Quiescent Current: The quiescent current is only 500µA, which significantly enhances the power efficiency, especially in battery-powered devices where power conservation is critical.
• Thermal Protection: The device includes thermal shutdown protection that safeguards the regulator from damage due to overheating, ensuring reliable operation under various thermal conditions.
• Stable with Low ESR Capacitors: The LT1175 is stable with low ESR output capacitors, providing flexibility in component selection and ensuring stable operation across different loads and temperatures.
