The Texas Instruments LP2981-28DBVT is a fixed-output, low-dropout (LDO) voltage regulator designed for efficient power management. It supports an input voltage range up to 16V and can deliver up to 100mA of output current.
This regulator offers a precise fixed output voltage of 2.8V with an accuracy of ±0.5% for new chip designs. Key electrical characteristics include a low quiescent current of 69µA at no load and a shutdown current below 1.75µA. It also provides essential protection features such as over current, over temperature, and short circuit protection.
The LP2981-28DBVT is supplied in a compact 5-pin SOT-23-5 package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C, making it versatile for various environmental conditions. The device is stable with 2.2µF ceramic capacitors, simplifying external component selection.
