Details

The LM150 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 3A over a 1.2V to 33V output range. They are exceptionally easy to use and require only 2 external resistors to set the output voltage. Further, both line and load regulation are comparable to discrete designs. Also, the LM150 is packaged in standard transistor packages which are easily mounted and handled.

In addition to higher performance than fixed regulators, the LM150 series offers full overload protection available only in IC's. Included on the chip are current limit, thermal overload protection and safe area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is accidentally disconnected.

Normally, no capacitors are needed unless the device is situated more than 6 inches from the input filter capacitors in which case an input bypass is needed. An output capacitor can be added to improve transient response, while bypassing the adjustment pin will increase the regulator's ripple rejection.

Besides replacing fixed regulators or discrete designs, the LM150 is useful in a wide variety of other applications. Since the regulator is “floating” and sees only the input-to-output differential voltage, supplies of several hundred volts can be regulated as long as the maximum input to output differential is not exceeded, i.e., avoid short-circuiting the output.

By connecting a fixed resistor between the adjustment pin and output, the LM150 can be used as a precision current regulator. Supplies with electronic shutdown can be achieved by clamping the adjustment terminal to ground which programs the output to 1.2V where most loads draw little current.

The part numbers in the LM150 series which have a NDS suffix are packaged in a standard Steel TO-3 package, while those with a NDE suffix are packaged in a TO-220 plastic package. The LM150 is rated for −55°C ≤ T_J ≤ +150°C, while the LM350A is rated for −40°C ≤ T_J ≤ +125°C, and the LM350 is rated for 0°C ≤ T_J ≤ +125°C.

FAQs

What is LM350AT?

The LM350AT is an adjustable three-terminal positive voltage regulator manufactured by Texas Instruments. It is capable of providing an output voltage range from 1.2V to 33V with a maximum output current of 3A, making it suitable for various voltage regulation applications.

How Does LM350AT Work?

The LM350AT regulates the output voltage by comparing a reference voltage to the feedback voltage from an external resistor divider network. It adjusts the output voltage by controlling the pass transistor to maintain a stable output even with varying input voltages and loads. The regulator provides protection features such as thermal shutdown and current limiting.

How Many Pins does LM350AT have and What are the Functions of the Pinout Configuration?

The LM350AT is available in a TO-220 package with three pins:

Input (Vin): The input voltage pin.
Output (Vout): The regulated output voltage pin.
Adjust (ADJ): The adjust pin for changing the output voltage (optional).

What are the Pros and Cons of LM350AT?

Pros:

High Output Current: Capable of delivering up to 3A of current.
Adjustable Output: Allows for a wide range of output voltages.
Thermal Shutdown: Includes thermal shutdown protection for overtemperature conditions.
Simple to Use: Three-terminal configuration simplifies circuit design.
Wide Application Range: Suitable for various voltage regulation needs.

Cons:

Heat Dissipation: May require a heatsink for high current and voltage drop applications.
Power Dissipation: Generates heat due to the voltage and current differentials, requiring thermal management.
External Components: Some applications may need additional capacitors or resistors for stability or filtering.

Are There Any Equivalents/Alternatives to LM350AT for Recommendation?

Alternatives to the LM350AT include the LM338 from Texas Instruments and the L7805CV from STMicroelectronics.
The LM317 is also a popular adjustable positive voltage regulator that can be used as an alternative.
