FAQs

What is LM1086CS-ADJ?

The LM1086CS-ADJ is a low dropout voltage regulator designed by Texas Instruments. It is an adjustable linear regulator capable of delivering up to 1.5A of output current with a low dropout voltage. The device is ideal for applications requiring a stable and adjustable output voltage, such as power supplies for microcontrollers, FPGAs, and other digital ICs.

How Does LM1086CS-ADJ Work?

The LM1086CS-ADJ regulates the input voltage to a stable and adjustable output voltage using a pass transistor and feedback control mechanism. It provides a low dropout voltage, ensuring proper regulation even when the input voltage is only slightly higher than the desired output voltage. The adjustable feature allows flexibility in setting the output voltage to the desired level.

How Many Pins does LM1086CS-ADJ have and What are the Functions of the Pinout Configuration?

The LM1086CS-ADJ is housed in a 3-lead TO-263 package. The pinout configuration includes:

  • ADJ: Adjustable output pin for setting the desired output voltage.
  • VOUT: Regulated output voltage pin.
  • VIN: Input voltage pin.
  • GND: Ground pin.

What are the Pros and Cons of LM1086CS-ADJ?

Pros:

  • High Output Current: Capable of delivering up to 1.5A of output current, suitable for many applications.
  • Low Dropout Voltage: Maintains regulation even with small input-to-output differentials.
  • Adjustable Output: Provides flexibility in setting the output voltage to the desired level.
  • Thermal Shutdown: Includes thermal overload protection for increased reliability.
