FAQs

What is LM317AHV?

The LM317AHV is a high-voltage, adjustable linear voltage regulator integrated circuit manufactured by Texas Instruments. It is designed to provide a regulated output voltage with a high input voltage capability, making it suitable for applications requiring precise voltage regulation in high-voltage environments.

How Does LM317AHV Work?

The LM317AHV operates by adjusting its output voltage based on a reference voltage and an external resistor divider network. It regulates the output voltage by controlling the pass transistor to maintain a stable voltage regardless of input variations. The adjustable feature allows for a wide range of output voltages to be set by the user.

How Many Pins does LM317AHV have and What are the Functions of the Pinout Configuration?

The LM317AHV is housed in a TO-39 metal can package with 3 pins. The pinout configuration includes:

  • Input (VIN): High-voltage input pin.
  • Adjust (ADJ): Adjust pin connected to external resistors for setting the output voltage.
  • Output (VOUT): Regulated output voltage pin.

What are the Pros and Cons of LM317AHV?

Pros:

  • High Voltage Capability: Designed to handle high input voltages for regulated output.
  • Adjustable Output: Allows users to set a wide range of output voltages.
  • Thermal Shutdown Protection: Built-in protection feature to prevent overheating.
  • Simple Circuit Design: Requires minimal external components for operation.

Cons:

  • Heatsinking: May require a heatsink for high-power applications to dissipate heat.
  • Dropout Voltage: Has a minimum required input-output voltage differential for proper regulation.

Are There Any Equivalents/Alternatives to LM317AHV for Recommendation?

  • The LM338 from Texas Instruments is a similar adjustable linear regulator with higher current capability.
  • Alternatives to the LM317AHV include the LT1086 from Analog Devices and the ADJ708 from Diodes Incorporated.
