LM309K STEEL/NOPB - Fixed LDO Voltage Regulator,
The LM309K STEEL/NOPB is a complete 5V Regulator fabricated on a single silicon chip. The device is designed for local regulation on digital logic cards, eliminating the distribution problems association with single-point regulation. The device is essentially blowout proof. Current limiting is included to limit the peak output current to a safe value. In addition, thermal shutdown is provided to keep the IC from overheating. If internal dissipation becomes too great, the regulator will shut down to prevent excessive heating. Considerable effort was expended to make this device easy to use and to minimize the number of external components. It is not necessary to bypass the output, although this does improve transient response somewhat. Input bypassing is needed, however, if the regulator is located very far from the filter capacitor of the power supply. Stability is also achieved by methods that provide very good rejection of load or line transients as are usually seen with TTL logic.
