LM is a fixed-voltage integrated-circuit voltage regulator designed for a wide range of applications. The L voltage regulator provides 9V Positive voltage as output and can provide local on-card regulation, eliminating the distribution problems associated with single-point regulation.

Although designed primarily as a fixed voltage regulator, but it can be used with external components to obtain adjustable voltage. Note: Complete Technical Details can be found in the datasheet given at the end of this page. Voltage regulators are very common in electronic circuits.

They provide a constant output voltage for a varied input voltage. The output current of this IC can go up to 1. But the IC suffers from heavy heat loss hence a Heat sink is recommended for projects that consume more current.

This is a typical application circuit of the IC.
