常見問題解答

What is LM1117MPX-33NOPB?

The LM1117MPX-33NOPB is a low dropout linear voltage regulator designed by Texas Instruments. It is specifically a 3.3V fixed output voltage regulator with a maximum dropout voltage of 1.2V at 800mA load current. It is commonly used to provide a stable 3.3V power supply in various electronic applications.

How Does LM1117MPX-33NOPB Work?

The LM1117MPX-33NOPB functions by regulating an input voltage to a precise 3.3V output voltage. It maintains this voltage regardless of variations in the input voltage or load current. The dropout voltage is the minimum required voltage difference between the input and output for the regulator to operate correctly.

How Many Pins does LM1117MPX-33NOPB have and What are the Functions of the Pinout Configuration?

The LM1117MPX-33NOPB is housed in an 8-pin TO-220 package. The pinout configuration includes:

  • IN: Input voltage pin.
  • OUT: Regulated 3.3V output voltage pin.
  • GND: Ground pin.
  • ADJ: Optional adjustable pin for external voltage setting (not used in fixed voltage version).

What are the Pros and Cons of LM1117MPX-33NOPB?

Pros:

  • Fixed Output Voltage: Provides a stable 3.3V output voltage, eliminating the need for external voltage regulation.
  • Low Dropout Voltage: Maintains regulation with a low dropout voltage, ensuring efficiency.
  • Thermal Shutdown Protection: Includes built-in thermal shutdown protection for added safety.
  • Simple Design: Easy to use with few external components required for operation.
  • Cost-Effective: Offers a cost-effective solution for voltage regulation in various applications.

Cons:

  • Fixed Voltage: Limited to 3.3V output, not suitable for applications requiring different output voltages.
  • Heat Dissipation: May require additional heat sinking for high current applications to dissipate heat effectively.
  • Current Limit: Limited maximum output current compared to higher power regulators.

Are There Any Equivalents/Alternatives to LM1117MPX-33NOPB for Recommendation?

  • The LD1117S33TR from STMicroelectronics is a similar 3.3V fixed voltage regulator.
  • Alternatives to the LM1117MPX-33NOPB include the L4931CZ33-AP from STMicroelectronics and the MAX8887EZK33+T from Maxim Integrated.
