LP2951CN Description

Short technical summary and product information.

The Texas Instruments LP2951CN is a versatile micropower voltage regulator designed for applications requiring a stable, adjustable output voltage. It can accept an input voltage range from 2.3V to 30V and deliver up to 100mA of output current.

 

Key electrical characteristics include a low dropout voltage of typically 380mV at 100mA, an extremely low quiescent current of 75µA, and high accuracy of 2.5%. The regulator provides tight load and line regulation, a very low temperature coefficient, and is stable with low-ESR output capacitors. It also includes protection features such as over current, over temperature, and short circuit protection.

 

This device supports both adjustable and fixed output voltage options, with fixed versions available at 3V, 3.3V, 5V, and 29V. The LP2951CN also features an enable pin for logic-controlled electronic shutdown and an error flag that warns of output dropout. It is suitable for use as a regulator or a voltage reference.

 

The LP2951CN is available in an 8-pin PDIP package and is designed for through-hole mounting. Its operating temperature range is -40°C to 125°C.
