Product Overview: Texas Instruments LP3961EMPX-3.3

The Texas Instruments LP3961EMPX-3.3 is a high-performance, fast-response voltage regulator designed to deliver a fixed output of 3.3 volts. This low-dropout (LDO) linear regulator is capable of providing up to 800mA of continuous load current, making it an ideal choice for a wide range of applications, from consumer electronics to industrial systems.

Key Features

• Output Voltage: Precisely regulated 3.3V output, suitable for logic ICs, microprocessors, and other digital circuits that require a stable voltage source.
• High Current Capability: The LP3961EMPX-3.3 can deliver up to 800mA of output current, catering to the needs of power-hungry devices.
• Low Dropout: With a low dropout voltage, this regulator operates efficiently even when the input voltage is very close to the output voltage, enhancing battery life in portable applications.
• Stable with Low-ESR Output Capacitors: It remains stable with ceramic capacitors, which are smaller, more reliable, and have lower equivalent series resistance (ESR) than other capacitor types.
• Thermal Protection: The built-in thermal shutdown feature protects the device from damage due to overheating.
• Overcurrent Protection: The current limit feature prevents the regulator from delivering excessive currents that could harm the connected components.
• Fast Transient Response: This regulator has been optimized for a fast transient response, which is critical for maintaining voltage stability during rapid load changes.
• Adjustable Output: While the device is primarily designed for a 3.3V output, it also offers the flexibility to adjust the voltage using external resistors.
