LP2985IM5-2.9/NOPB - Texas Instruments

The LP2985IM5-2.9/NOPB is a fixed-output, low-dropout (LDO) voltage regulator from Texas Instruments, designed to deliver a stable 2.9V output from a wider input voltage range. This high-performance regulator is ideal for portable and battery-powered applications due to its low power consumption and small surface-mount package.

Key Features

• Output Voltage: Precisely regulated 2.9V output, which is ideal for consistent performance in sensitive electronics.
• High Accuracy: Output voltage accuracy is maintained within ±0.5% over temperature, line, and load variations, ensuring reliable operation under various conditions.
• Low Dropout: The LDO can operate with a very small input-to-output voltage differential, which minimizes power loss and improves efficiency.
• Low Quiescent Current: With a typical quiescent current of 850µA, this device is optimized for battery-powered applications where power conservation is critical.
• Thermal Shutdown Protection: The built-in thermal shutdown feature protects the device from damage due to overheating.
• Current Limit Protection: The current limit protection helps prevent damage to the device and the load during fault conditions.
• Stable with Low-ESR Capacitors: The LP2985IM5-2.9/NOPB is stable with ceramic capacitors, which reduces the overall size and cost of the power supply design.
• Noise Reduction: A bypass pin enables the addition of an external noise bypass capacitor for ultra-low noise performance, making it suitable for RF and precision analog applications.
