Frequently Asked Questions
What is the output voltage and current rating of the LM340SX-5.0/NOPB?
The LM340SX-5.0/NOPB provides a fixed 5V output voltage with a maximum continuous output current of 1.5A. It includes internal current limiting to protect against overload conditions, making it suitable for powering microcontrollers, logic ICs, and other 5V loads.
What input voltage range does the LM340SX-5.0/NOPB support?
The LM340SX-5.0/NOPB accepts an input voltage from 7V to 35V (absolute maximum 35V). The nominal dropout voltage is 2V, so a minimum input of approximately 7V is required to maintain a regulated 5V output across the full load range.
What package does the LM340SX-5.0/NOPB use and is it RoHS compliant?
The LM340SX-5.0/NOPB is supplied in a D2PAK (TO-263-3) surface-mount package, indicated by the 'SX' suffix. It is Pb-free (YTEOL rating of 15), though it is marked as Not Compliant with REACH regulations, so designers should verify suitability for their specific application and regional requirements.
What protection features does the LM340SX-5.0/NOPB include?
The LM340SX-5.0/NOPB integrates internal thermal shutdown, output current limiting, and safe-area compensation. These features protect the device and downstream circuitry during fault conditions such as short circuits or excessive power dissipation, improving system reliability without requiring external protection components.
What are common applications for the LM340SX-5.0/NOPB?
The LM340SX-5.0/NOPB is commonly used in industrial power supplies, embedded system boards, automotive accessories, sensor modules, and communication interface circuits. Its stable 5V fixed output and 1.5A drive capability make it an excellent choice for biasing microcontrollers, FPGAs, and digital logic devices.
