LP2981-30DBVR Description

Short technical summary and product information.

The Texas Instruments LP2981-30DBVR is a 100mA, low-dropout (LDO) linear voltage regulator designed for various applications requiring a stable 3V output. It operates with an input voltage range up to 16V and features a typical dropout voltage of 0.37V at 100mA. The device includes an enable pin for control and protection features such as over current, over temperature, and short circuit protection.

 

Packaged in a compact SOT-23-5 surface-mount package, the LP2981-30DBVR is suitable for space-constrained designs. Its operating temperature range is -40°C to 125°C, making it robust for demanding environments. The regulator provides a fixed output voltage of 3V with a typical quiescent current of 0.065mA and a PSRR of 63dB at 1kHz.

 

This LDO regulator is ideal for power management in battery-powered devices, portable electronics, and other applications where efficient and stable voltage regulation is critical. Its fixed output and enable functionality simplify circuit design and power sequencing.
