NTE Electronics, Inc. Voltage Regulators - Linear LM317T

The LM317T is a 3-terminal adjustable positive voltage regulator designed to provide an output current exceeding 1.5A across a voltage range of 1.2V to 37V. It is housed in a TO-220 package and features superior line and load regulation compared to standard fixed regulators. The device includes built-in overload protection mechanisms such as current limiting, thermal overload protection, and safe area protection, which remain operational even if the adjustment terminal is disconnected. This voltage regulator is versatile, allowing for applications beyond simple voltage regulation, including adjustable switching regulators and precision current regulation by connecting a fixed resistor between the adjustment and output terminals. The LM317T typically requires no external capacitors unless located far from input filter capacitors, although an optional output capacitor can enhance transient response. It also offers high ripple rejection ratios, making it suitable for various electronic applications. The device operates within a temperature range of 0¬8C to +125¬8C and has a maximum input-output voltage differential of 40V.
