Product Overview: Texas Instruments LP3961ES-2.5

The Texas Instruments LP3961ES-2.5 is a highly reliable and efficient low-dropout linear regulator designed to deliver a fixed output voltage of 2.5V with an output tolerance of ±1% over line, load, and temperature. It is capable of supplying an impressive 800mA of output current, making it suitable for a wide range of applications, from consumer electronics to industrial systems.

This regulator features a low dropout voltage, typically just 350mV at a 800mA load, which enhances its efficiency and allows it to operate effectively even when the input voltage is close to the output voltage. This characteristic is particularly beneficial in battery-powered devices, where maximizing the usage of available power is crucial.

Key Features

• Output Voltage: Fixed 2.5V with high accuracy.
• Output Current: Capable of delivering up to 800mA.
• Low Dropout Voltage: Typically 350mV at full load, which is ideal for battery-operated devices.
• Thermal Protection: Built-in thermal shutdown protection safeguards the device from overheating.
• Stable with Low ESR Capacitors: The LP3961ES-2.5 is stable with ceramic capacitors, which are smaller, more reliable, and have lower equivalent series resistance (ESR) than other types of capacitors.
• Adjustable Current Limit: The current limit is user-adjustable, providing additional protection for the regulator and the load.

Applications

The LP3961ES-2.5 is versatile and can be implemented in a variety of applications, including:

• Consumer Electronics
• Portable Devices
• Wireless LAN and DSL Modems
• PC Add-On Cards
• Industrial Equipment

With its precision output voltage, low dropout, and robust protection features, the Texas Instruments LP3961ES-2.5 is an optimal solution for systems requiring a stable and efficient power supply. Its small TO-263 package makes it suitable for space-constrained applications while providing excellent thermal performance.
