L149V Description

Short technical summary and product information.

The STMicroelectronics L149V is a general-purpose power booster designed for applications requiring high output current. It features a quasi-complementary Darlington output stage and an inhibit facility.

 

Key electrical characteristics include a high output current of 4A peak, a high current gain of 10,000 (typ), and operation up to ±20V. The device also boasts a high slew rate of 30 V/ms and a power bandwidth of 200 KHz. Protection features include thermal and short circuit protection, ensuring reliable operation within the Safe Operating Area (SOA).

 

The L149V is particularly suited for use with operational amplifiers in closed-loop configurations to increase output current. It is housed in a Pentawatt-5 package and is designed for through-hole mounting.

 

This linear driver is suitable for various audio and power amplification circuits where a robust and high-current output stage is required.
