Details

The LT1083 series of positive adjustable regulators aredesigned to provide 3A, 5A and 7.5A with higher efficiencythan currently available devices. All internal circuitry isdesigned to operate down to 1V input to output differentialand the dropout voltage is fully specified as a function ofload current. Dropout is guaranteed at a maximum of 1.5Vat maximum output current, decreasing at lower loadcurrents. On-chip trimming adjusts the output voltage to1%. Current limit is also trimmed, minimizing the stresson both the regulator and power source circuitry underoverload conditions.FEATURES■ Three-Terminal 3.3V, 3.6V, 5V and 12V■ Output Current of 3A, 5A or 7.5A■ Operates Down to 1V Dropout■ Guaranteed Dropout Voltage at Multiple Current Levels■ Line Regulation: 0.015%■ Load Regulation: 0.1%■ 100% Thermal Limit Functional Test■ Adjustable Versions AvailableAPPLICATIONS■ High Efficiency Linear Regulators■ Post Regulators for Switching Supplies■ Constant Current Regulators■ Battery Chargers

FAQs

What is LT1084CT-5?

The LT1084CT-5 is a low dropout voltage regulator IC manufactured by Linear Technology (now part of Analog Devices). It is designed to provide a stable output voltage with low dropout voltage, making it suitable for applications requiring precise voltage regulation.

How Does LT1084CT-5 Work?

The LT1084CT-5 operates by taking an input voltage, regulating it to a specified output voltage level, and maintaining that level even when the input voltage varies within a certain range. It utilizes a feedback loop to adjust its internal circuitry to ensure a constant output voltage, thus providing a stable power supply for connected components.

How Many Pins does LT1084CT-5 have and What are the Functions of the Pinout Configuration?

The LT1084CT-5 comes in a TO-220 package with 3 pins. The pinout configuration includes:

  • Input (VIN): Pin for the input voltage.
  • Output (VOUT): Pin for the regulated output voltage.
  • Adjust (ADJ): Pin for adjustment or feedback control.

What are the Pros and Cons of LT1084CT-5?

Pros:

  • Low Dropout Voltage: Allows the regulator to maintain a stable output voltage even when the input voltage is close to the output voltage.
  • Precision Voltage Regulation: Provides accurate and stable output voltage for sensitive electronic components.
  • Thermal Protection: Includes built-in thermal shutdown protection to prevent overheating.

Cons:

  • Heat Dissipation: May require heat sinking for high power applications due to the voltage drop across the regulator.
  • Operating Temperature: Performance may be affected at extreme temperature ranges.

Are There Any Equivalents/Alternatives to LT1084CT-5 for Recommendation?

Some equivalents or alternatives to the LT1084CT-5 include the LM2940 from Texas Instruments and the LM1084 from National Semiconductor.
