The LM340T5 is a versatile positive voltage regulator IC that provides a fixed 5V output. It is designed with internal current-limiting, thermal shutdown, and safe-area compensation, making it highly reliable for various applications. With adequate heat sinking, this regulator can supply over 1.0A of output current.
Key electrical specifications include an output voltage tolerance of ±2% at 25°C and ±4% over the temperature range. It also features line regulation of 0.01%/V and load regulation of 0.3%/A. These specifications ensure a stable and consistent output voltage under varying input conditions and load demands.
The LM340T5 is available in multiple package types, including TO-3 (metal can), TO-263 (surface-mount), TO-220 (power package), and 3-lead SOT-223 (surface-mount). This variety allows for flexibility in PCB design and thermal management strategies. As a linear regulator, it dissipates heat, so heat sinks are recommended for high-current applications to prevent overheating.
This IC is commonly used in projects requiring a constant +5V supply for microcontrollers, sensors, and other digital or analog circuitry. It can also be configured with external components to create adjustable voltage regulators or current limiters.
