LP2981AIM5-3.3 Description

Short technical summary and product information.

The Texas Instruments LP2981AIM5-3.3 is a low-dropout (LDO) linear voltage regulator. It provides a stable 3.3V output voltage with a maximum output current of 100mA. The device features a low quiescent current of 95µA, making it suitable for power-sensitive applications.

 

Key electrical characteristics include an input voltage range up to 16V and a dropout voltage of 0.37V at 100mA. Protection features such as over current, over temperature, and short circuit protection are integrated for enhanced reliability. The regulator also offers a Power Supply Rejection Ratio (PSRR) of 63dB at 1kHz.

 

This component is supplied in a SOT-23-5 surface mount package, also referred to as SC-74A or SOT-753. The operating temperature range is from -40°C to 125°C. Its fixed output and robust protection make it a reliable choice for various electronic designs.
