LM340SX-5.0/NOPB Description

Short technical summary and product information.

The LM340SX-5.0/NOPB from Texas Instruments is a monolithic 3-terminal positive voltage regulator designed for a wide range of applications. This linear regulator provides a fixed 5V output with an output current capability of up to 1.5A.

 

Key electrical specifications include a maximum input voltage of 35V and a typical quiescent current of 8mA. It offers robust protection features such as internal thermal overload and short-circuit protection, making it a reliable choice for power management.

 

This component is housed in a TO-263-3 (DDPAK/TO-263-3) surface-mount package, facilitating integration into compact designs. The operating temperature range is from 0°C to 125°C. Output capacitance is not required for stability, simplifying circuit design.

 

The LM340SX-5.0/NOPB is intended for local (on-card) regulation to eliminate noise and distribution problems associated with single-point regulation. It can also be used with external components to obtain adjustable output voltages and currents.
