Product Overview: LP3981IMM-2.8

The LP3981IMM-2.8 is a low-dropout CMOS linear regulator that offers a high-quality power supply solution for applications requiring a low noise and low quiescent current. Manufactured by Texas Instruments, a leader in semiconductor design and production, this regulator is designed to deliver a fixed output voltage of 2.8V with an input voltage range from 2.7V to 6V.

Key Features

• Output Voltage: Fixed 2.8V with high accuracy.
• Output Current: Capable of delivering up to 300mA of continuous current.
• Low Dropout Voltage: Maintains regulation with minimal difference between the input and output voltage, enhancing efficiency.
• Stable with Ceramic Capacitors: Compatible with cost-effective ceramic capacitors, which are smaller and have better temperature characteristics than other types.
• Low Quiescent Current: Ideal for battery-powered devices due to its low consumption when active and in shutdown mode.
• Fast Start-Up Time: Ensures quick turn-on response, suitable for applications that require rapid power-up sequences.
• Thermal Shutdown and Overcurrent Protection: Built-in safety features to protect the device and the load from adverse conditions.
