STMicroelectronics LM317D2T Adjustable Linear Voltage Regulator, 1.2V to 37V, 2
STMicroelectronics LM317D2T adjustable voltage regulator (1.2-37V, 2.2A). Features 0.1% regulation, current limit & thermal protection in D²PAK package.
The STMicroelectronics LM317D2T-TR is a highly versatile, positive adjustable linear voltage regulator designed for robust performance in a wide array of electronic applications. This integrated circuit is engineered to supply a load current exceeding 1.5A, with the output voltage being easily adjustable across a broad range of 1.2V to 37V. This flexibility makes it an invaluable component, eliminating the need to stock numerous fixed-voltage regulators and simplifying design and inventory management.
A key advantage of the LM317D2T is its exceptional ease of use. The nominal output voltage is set using a simple external resistive divider, allowing for precise and custom voltage supply creation. The device boasts outstanding regulation characteristics, featuring 0.1% line and load regulation for stable and reliable output even with fluctuations in input voltage or load conditions.
Robust Protection Features
Built for reliability, this regulator incorporates comprehensive protection mechanisms to ensure safe operation. These include current limiting to prevent overload damage, thermal shutdown to protect against overheating, and Safe Operating Area (SOA) control. Its design also supports floating operation, making it suitable for high-voltage applications where the regulator is not directly referenced to ground.
Housed in a robust 3-pin D²PAK (TO-263-3) surface-mount package, it offers excellent thermal performance and power dissipation capabilities, ideal for power supply designs requiring a compact footprint with substantial output current.
