The LP3876ET-2.5/NOPB is a high-performance, low-dropout (LDO) regulator from Texas Instruments designed to meet the stringent requirements of modern electronic equipment. This regulator offers a fixed output voltage of 2.5V, with an output current capability of up to 3A, making it ideal for a wide range of applications, including but not limited to, servers, networking equipment, and industrial systems.

Key Features

• High Output Current: Capable of delivering up to 3A of continuous output current.
• Low Dropout Voltage: Ensures efficient operation even with a minimal difference between the input and output voltage, which is critical for battery-powered devices.
• Stable with Low ESR Output Capacitor: The LP3876ET-2.5/NOPB is stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than traditional tantalum or aluminum electrolytic capacitors.
• Overcurrent and Overtemperature Protection: Includes built-in protection features that safeguard the device and the load from adverse conditions.
• Adjustable Output Voltage: While the device is offered with a fixed 2.5V output, it also provides the flexibility to adjust the output voltage using external resistors.
• Fast Transient Response: The regulator responds quickly to changes in load, maintaining output voltage stability.
• Power Good (PG) Output: Offers a PG signal to indicate when the output voltage is within its nominal range, which is useful for power sequencing in complex systems.

Applications

The LP3876ET-2.5/NOPB is particularly suited for applications that require a high current, low voltage supply with a fast transient response. This includes:

• High-end servers
• Networking equipment such as routers and switches
• Industrial equipment
• FPGA, DSP, and ASIC power supplies
• Memory, logic, and motherboard power supplies

Quality and Reliability

As with all Texas Instruments products, the LP3876ET-2.5/NOPB is designed to meet the highest standards of quality and reliability. It is offered in a thermally-enhanced TO-220 package and is characterized for operation from -40°C to 125°C, ensuring performance in a wide range of environmental conditions.
