LP3985ITL-3.3 Description

Short technical summary and product information.

The Texas Instruments LP3985ITL-3.3 is a high-performance, 150mA micropower, low-noise, ultra-low-dropout (LDO) CMOS voltage regulator. It is designed for battery-powered applications where low quiescent current is critical. The device features a wide input voltage range from 2.5V to 6V and offers fixed output voltages, including 3.3V.

 

Key electrical characteristics include a typical output noise of 30 µVrms over 10 Hz to 100 kHz and a Power Supply Rejection Ratio (PSRR) of 42 dB at 100 KHz. The dropout voltage is typically 60mV at a 150mA load, ensuring efficient operation even under varying load conditions. The regulator has an accuracy of 2% and requires a minimum load capacitance of 1µF for stability.

 

Available in DSBGA and SOT-23 packages, the LP3985ITL-3.3 is suitable for space-constrained applications. It operates over a wide temperature range of -40°C to 125°C. The device includes features such as logic-controlled enable, thermal shutdown, and short-circuit current limit for enhanced protection and control.
