LM309 Datasheet (National Semiconductor)

LM309, 5-Volt Regulator

The LM109 series are complete 5V regulators fabricated on a single silicon chip.

They are designed for local regulation on digital logic cards, eliminating the distribution problems association with single-point regulation.

The devices are available in two standard transistor packages.
