LP2985-18DBVR Description

Short technical summary and product information.

The Texas Instruments LP2985-18DBVR is a linear, low-dropout (LDO) voltage regulator designed for various power management applications. It offers a fixed output voltage of 1.8V and can supply up to 150mA of current.

 

Key electrical specifications include an input voltage range of 2.5V to 16V (new chip) and a typical dropout voltage of 280mV at 150mA. The regulator features low noise (30µVRMS) and high PSRR (70dB at 1kHz), making it suitable for noise-sensitive applications. It also includes protection features such as over current, over temperature, and short circuit protection.

 

The LP2985-18DBVR is available in a compact 5-pin SOT-23-5 (DBV) surface-mount package. Its operating temperature range is -40°C to 125°C, ensuring reliable performance in demanding environments. The device also features an enable pin for power control.
