The LP3876ESX-2.5 is a high-performance, low-dropout regulator designed and manufactured by Texas Instruments. This component is part of the LP3876 series, which provides precision, low-dropout voltage regulation with a low noise output, making it an excellent choice for sensitive applications that require a stable power supply.

Key Features

• Output Voltage: The device provides a fixed output voltage of 2.5V, suitable for a variety of digital and analog circuits.
• High Current Capability: It can deliver up to 3A of continuous output current, ensuring sufficient power for demanding loads.
• Low Dropout Voltage: The low dropout voltage allows for efficient operation even when the input voltage is close to the output voltage, reducing power loss and improving overall efficiency.
• Stable with Low ESR Output Capacitors: The regulator is stable with ceramic capacitors, which have lower equivalent series resistance (ESR) than traditional tantalum or aluminum electrolytic capacitors.
• Fast Transient Response: The device's fast transient response ensures stable voltage levels during rapid changes in load, which is critical for high-performance processors and other sensitive components.
• Thermal Protection: Built-in thermal shutdown protection safeguards the device from damage due to overheating.
• Adjustable Versions: While the LP3876ESX-2.5 offers a fixed voltage, the series also includes adjustable versions for applications requiring a custom voltage setting.
