LM317L ADJUSTABLE VOLTAGE REGULATOR SOP-8

The LM317L SOP-8 is a miniature adjustable voltage regulator. It excels at regulating and maintaining a steady voltage output within a designated range. This capability makes it a prevalent choice for powering various electronic circuits, ensuring consistent voltage levels for optimal performance. The SOP-8 package makes it suitable for space-constrained projects where board size is a premium.

Key Features of the LM317L adjustable voltage regulator SOP-8:

• • Adjustable Output Voltage: Unlike fixed voltage regulators, the LM317L SOP-8 empowers you to tailor the output voltage to your specific needs. This is achieved through the implementation of an external resistor network, granting a broad output voltage range (typically 1.25V to 32V for the LM317L).
  • Positive Voltage Regulation: The LM317L SOP-8 specializes in regulating and supplying a positive voltage at its output terminal.
  • Lower Output Current Capacity: Compared to the standard LM317 (1.5A), the LM317L offers a lower output current capability, typically in the range of 100mA to 300mA (depending on the specific variant). This makes it suitable for powering lower-current devices.
  • Internal Protective Features: The LM317L SOP-8 incorporates safeguards such as current limiting, thermal overload protection, and safe operating area (SOA) protection. These features contribute to the device’s reliability and durability in various operating conditions.
  • Compact SOP-8 Package: This surface-mount package boasts a smaller footprint compared to through-hole options, allowing for denser circuit designs on PCBs with limited space.
