LP2985A-18DBVR Description

Short technical summary and product information.

The Texas Instruments LP2985A-18DBVR is a linear voltage regulator designed for various applications requiring a stable 1.8V output. It can supply up to 150mA of current and operates with an input voltage range of 2.2V to 16V.

 

Key electrical characteristics include a low dropout voltage of 0.58V at 150mA and a typical quiescent current of 95 µA. The regulator features enable control and protection against over current, over temperature, and short circuits. Its noise performance is rated at 30 µVrms with a PSRR of 45dB at 1kHz.

 

This component is housed in a SOT-23-5 surface-mount package, making it suitable for space-constrained designs. The operating temperature range is -45°C to 125°C, ensuring reliability in demanding environments.

 

The LP2985A-18DBVR is a single-output positive voltage regulator, ideal for power management in portable electronics and other systems requiring efficient voltage regulation.
