LP3985IM5X-3.0/NOPB Description

Short technical summary and product information.

The Texas Instruments LP3985IM5X-3.0/NOPB is a micropower, 150mA ultra-low-dropout CMOS voltage regulator. It provides a stable, fixed 3V output voltage from an input range of 2.5V to 6V.

 

Key electrical specifications include a maximum output current of 150mA, a typical dropout voltage of 60mV at 150mA load, and a low quiescent current of 0.085mA. The regulator features a low output noise of 30 µVrms and a high Power Supply Rejection Ratio (PSRR) of 42dB at 100 KHz. It also includes an enable pin for standard logic control and protection features such as over current, over temperature, and short circuit.

 

This device is available in a SOT-23-5 package, suitable for surface mounting. The operating temperature range is -40°C to 125°C. It is designed to be stable with ceramic and high-quality tantalum capacitors, making it suitable for various power management applications where low noise and stable voltage are critical.
