LP3985IM5-2.8 Description

Short technical summary and product information.

The LP3985IM5-2.8 from Texas Instruments is a highly efficient linear voltage regulator designed for portable and wireless applications demanding high performance and small size. It delivers a stable 2.8V output with a maximum output current of 150mA.

 

Key electrical characteristics include an ultra-low dropout voltage of 0.1V at 150mA load, ensuring minimal power loss and extended battery life. The regulator exhibits low output noise of 30 µVrms over a 10 Hz to 100 kHz bandwidth and offers good power supply rejection ratio (PSRR) of 50dB at 1kHz. It operates within an input voltage range of 2.5V to 6V and features a quiescent current of only 85 nA when shut down.

 

Designed for ease of use, the LP3985IM5-2.8 includes an enable pin for logic-controlled operation and is stable with small ceramic or high-quality tantalum output capacitors. Protection features include over-current and thermal shutdown.

 

This device is supplied in a compact SOT-23-5 package, making it suitable for space-constrained designs. The surface mountable package and standard pinout facilitate integration into various electronic circuits.
