LP3961EMP-1.8 Description

Short technical summary and product information.

The Texas Instruments LP3961EMP-1.8 is a high-accuracy, low-dropout (LDO) linear voltage regulator designed for efficient power management. It operates with an input voltage range of 2.5V to 7V and delivers a stable, fixed output voltage of 1.8V at up to 800mA.

 

Key electrical characteristics include a typical dropout voltage of 240mV at 800mA and a low quiescent current of 4mA. The regulator features an enable control pin for power sequencing and shutdown capabilities. Protection features such as overcurrent, overtemperature, and short-circuit protection are integrated for enhanced reliability.

 

This device is suitable for applications requiring a stable and low-noise power supply. The LP3961EMP-1.8 is supplied in a compact SOT-223-5 surface-mount package, making it ideal for space-constrained designs. Its operating temperature range is -40°C to 125°C.
