LM340SX-5.0/NOPB Datasheet

Linear Regulators - Standard


The LM340SX-5.0/NOPB monolithic 3-terminal positive voltage regulators employ internal current-limiting, thermal shutdown and safe-area compensation, making them essentially indestructible. If adequate heat sinking is provided, they can deliver over 1.OA output current. They are intended as fixed voltage regulators in a wide range of applications including local (on-card) regulation for elimination of noise and distribution problems associated with single-point regulation. In addition to use as fixed voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents. Considerable effort was expended to make the entire series of regulators easy to use and minimize the number of external components. It is not necessary to bypass the output, although this does improve transient response. Input bypassing is needed only if the regulator is located far from the filter capacitor of the power supply. The 5V, 12V, and 15V regulator options are available in the steel TO-3 power package. The LM340SX-5.0/NOPB is available in the TO-220 plastic power package, and the LM340SX-5.0/NOPB is available in the SOT-223 package, as well as the LM340SX-5.0/NOPB in the surface-mount DDPAK/TO-263 package.
