LP2981A-50 Description

Short technical summary and product information.

The Texas Instruments LP2981A-50 is a fixed-output, low-dropout linear voltage regulator designed for portable and non-portable applications. It provides a stable 5V output with a tolerance of 0.75% for the A-grade devices and can deliver up to 100mA of continuous load current.

 

Key electrical specifications include an ultra-low dropout voltage, typically 200mV at full load, and a low quiescent current of 600µA. The device operates over a wide temperature range of -40°C to 125°C. It also includes standard regulator features such as overcurrent and overtemperature protection.

 

The LP2981A-50 is supplied in a compact SOT-23-5 surface-mount package, making it suitable for space-constrained designs. Its robust performance and reliable operation make it a cost-effective choice for various power management needs.
