LD2981ABM50TR Description

Short technical summary and product information.

The LD2981ABM50TR from STMicroelectronics is a linear voltage regulator designed for power management applications. It provides a stable, fixed 5V output voltage with a maximum output current of 100mA. The device features a low dropout voltage of 0.375V at 100mA, making it suitable for battery-powered devices where efficiency is critical.

 

Key electrical characteristics include a quiescent current of 150 µA and a supply current of up to 2.6 mA. It also offers a Power Supply Rejection Ratio (PSRR) of 63dB at 1kHz, helping to filter out noise from the power supply. Protection features include over-current and over-temperature shutdown, enhancing device reliability.

 

This voltage regulator operates over a wide temperature range of -40°C to 125°C. It is housed in a compact SOT-23-5 (SC-74A, SOT-753) surface-mount package, ideal for space-constrained designs. The 'Enable' control feature allows for power sequencing and management.

 

Environmental compliance includes RoHS3 status, REACH unaffected, and Moisture Sensitivity Level 1. The LD2981ABM50TR is suitable for various applications requiring a reliable and efficient voltage regulation solution.
