LP3981IMM-3.0 Description

Short technical summary and product information.

The Texas Instruments LP3981IMM-3.0/NOPB is a high-accuracy, low-dropout (LDO) linear voltage regulator designed for battery-powered applications. It provides a stable 3V output with up to 300mA of current from an input voltage range of 2.5V to 6V.

 

Key electrical characteristics include a low quiescent current of less than 1µA when shut down, and a typical dropout voltage of 132mV at a 300mA load. The regulator also features high power supply rejection ratio (PSRR) of 60dB at 1kHz, and low output noise of 35µVrms over a 10Hz to 100kHz bandwidth, making it suitable for noise-sensitive applications.

 

Protection features include over current, over temperature, and short-circuit current limiting. The device is controlled via a logic-level enable pin. It is stable with ceramic and high-quality tantalum capacitors.

 

This regulator is available in an 8-pin VSSOP package, suitable for surface mounting. Performance is specified over a wide temperature range of -40°C to 125°C.
