L149 Description

Short technical summary and product information.

The ST L149 is a general-purpose linear driver designed to increase output current when used with an operational amplifier in a closed-loop configuration. It features a high output current capability of up to 4A peak and a high slew rate of 30 V/μs.

 

Key electrical characteristics include a supply voltage range of up to ±20V, a DC output current of 3A, and a high current gain (hFE) typically ranging from 6000 to 10000. The device also incorporates thermal protection and short-circuit protection, operating within the Safe Operating Area (SOA).

 

The L149 is housed in a Pentawatt package, suitable for through-hole mounting. Its design makes it particularly useful for applications requiring significant current boosting from an op-amp.

 

This linear driver is well-suited for power amplifier stages and other applications where increased output current is necessary.
