Frequently Asked Questions

What is the output voltage of the LM2990T-12?

The LM2990T-12 provides a fixed negative output voltage of -12V, making it suitable for analog circuits, op-amps, and split-supply power systems that require a stable negative rail.

What is the input voltage range for the LM2990T-12?

The LM2990T-12 requires an input voltage between 13V and 26V (absolute maximum 26V). The dropout voltage is typically 0.6V and 1V maximum, so the input must be at least 1V more negative than the output.

What package does the LM2990T-12 use?

The LM2990T-12 comes in a TO-220 3-pin through-hole package, which offers excellent thermal dissipation and is easy to mount on standard PCBs with or without a heatsink.

What are typical applications for the LM2990T-12?

Typical applications include split-supply power designs for op-amps and instrumentation amplifiers, audio equipment, industrial control systems, telecom power supplies, and medical instrumentation requiring a regulated -12V negative rail.

Is the LM2990T-12 RoHS compliant?

Yes, the LM2990T-12 is Pb-free and RoHS compliant, as indicated by its Pbfree Code: Yes. It has been in production since 1993, ensuring long-term supply availability.
