The Texas Instruments LP3985IM5-3.3/NOPB is a high-performance, low-noise, ultra-low-dropout (LDO) linear voltage regulator designed for various applications. It can supply 150 mA of current while maintaining a low dropout voltage, typically 100 mV at a 150 mA load. The device features a wide input voltage range from 2.5V to 6V and offers fixed output voltage options, including 3.3V for this specific part number.
Key electrical characteristics include a typical quiescent current of 85 µA, which drops to 1.5 µA when shut down, making it suitable for power-sensitive applications. It boasts a high Power Supply Rejection Ratio (PSRR) of 42 dB at 100 kHz and 50 dB at 1 kHz, ensuring clean power delivery. The output noise is a low 30 µVrms over a 10 Hz to 100 kHz bandwidth.
This regulator is available in compact packages such as DSBGA and SOT-23, supporting surface mount installation. It operates across a wide temperature range of -40°C to 125°C and includes features like thermal shutdown and short-circuit current limit for enhanced reliability. The enable pin allows for standard logic control, and it is stable with ceramic and high-quality tantalum capacitors.
