LM109/LM309 5-Volt
Regulator
General Description
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.
In the solid-kovar TO-5 header, it can deliver output currents in excess of 200 mA, if adequate heat sinking is provided.
With the TO-3 power package, the available output current is greater than 1A.
The
regulators are essentially blowout proof.
Current limiting is included to limit the peak output current to a safe valu...
