LM317EMPX/EMSN Typical application Circuitry

LM317EMPX/EMSN

The LM317EMPX/EMSN is part of the LM317 series of adjustable voltage regulators. This series is well-regarded for its ability to provide an adjustable output voltage, and it is widely used across various manufacturers. The LM317EMPX/EMSN variant is specifically designed for applications that require a smaller package and is capable of delivering up to 1.5 A of load current. This makes it suitable for applications like power supplies, battery chargers, and motor control circuits where space is at a premium but a reliable and adjustable power supply is needed.

1. Input (Pin 1): This pin is where the input voltage is supplied. The voltage at this pin should be higher than the desired output voltage by at least the dropout voltage of the LM317EMPX/EMSN, but also within the maximum input voltage limit of the device.

2. Output (Pin 2): This pin provides the output voltage that is controlled. To set the output voltage, connect a resistor (R1) from this pin to the adjust pin (Pin 3), and another resistor (R2) from the adjust pin to ground. The following calculation yields the output voltage: Vout = 1.25V (1 + R2/R1) + Iadj R2.

3. Adjust (Pin 3): This pin is used for adjusting the output voltage. The connection of resistors R1 and R2 between this pin, the output, and ground allows for setting the desired output voltage.

4. Key Features of the LM317EMPX/EMSN:

- Adjustable Output Voltage: The LM317EMPX/EMSN offers the ability to adjust the output voltage to a desired level using external resistors.

- Compact Form Factor: It is perfect for situations where space is limited because of its lower package size.

- High Current Capability: Capable of delivering up to 1.5 A, it is suitable for a range of medium-power requirements.

- Built-In Protection: Features like thermal overload protection and safe operating area protection are included for enhanced reliability.

5. Design Considerations for the LM317EMPX/EMSN: When designing with the LM317EMPX/EMSN, it's important to reference the datasheet for specific voltage and current specifications. The selection of resistors R1 and R2 is crucial for setting the correct output voltage. Additionally, ensure the input voltage is always higher than the output voltage by at least the dropout voltage. Adequate heat sinking may also be necessary, especially when the device is operating close to its maximum load current capacity.

In summary, the LM317EMPX/EMSN is a versatile and compact adjustable voltage regulator, suitable for various applications where an adjustable power supply is needed in a smaller form factor. Its ability to provide a regulated output voltage with a simple resistor setup makes it a popular choice in electronic circuit designs.
