LP2985IM5-3.1 Description

Short technical summary and product information.

The LP2985IM5-3.1 from Texas Instruments is a micropower, low-noise, ultra-low-dropout linear voltage regulator designed for battery-powered applications. It delivers up to 150 mA of output current with a low dropout voltage.

 

Key electrical specifications include an input voltage range of 2.5 V to 16 V and a typical quiescent current of 75 µA at 1 mA load, reducing to less than 1 µA when shut down. The device offers high power supply rejection ratio (PSRR) and is stable with low-ESR output capacitors, such as 2.2 µF ceramic types. Protection features include overcurrent and overtemperature protection.

 

This regulator is available in a compact SOT-23-5 surface-mount package, making it suitable for space-constrained designs. The operating temperature range is -40°C to 125°C. Applications include cellular phones, portable computers, and personal digital assistants.
