詳細說明

The LDL212PUR is a dependable power management solution that offers a maximum current output of 1.2 A within a wide input voltage range of 2.5 V to 18 V. With a remarkably low dropout voltage of 350 mV @ 1.2 A, this device ensures efficient power delivery under various operating conditions. Its impressive power supply rejection ratio of 87 dB at 120 Hz and over 40 dB at 100 kHz makes it well-suited for use in switched-mode power supplies (SMPS) and as a secondary linear regulator in DC-DC converters. Additionally, the LDL212 features an enable logic control function that puts the device into shutdown mode, reducing overall power consumption when not in use. To enhance its reliability, the device comes equipped with current limit, safe operating area (SOA), and thermal protection mechanisms

常見問題解答

What is LDL212PUR?

The LDL212PUR is a high-current, low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. It is designed to provide stable and regulated output voltage with a low dropout voltage, making it suitable for power management applications in various electronic devices.

How Does LDL212PUR Work?

The LDL212PUR regulates the output voltage by comparing a reference voltage to the feedback voltage from the output. It adjusts the pass device to maintain a constant output voltage, even when the input voltage or load conditions change. The low dropout characteristic ensures efficient regulation even with small voltage differentials between the input and output.

How Many Pins does LDL212PUR have and What are the Functions of the Pinout Configuration?

The LDL212PUR is available in a compact 5-pin SOT-223 package. The pinout configuration includes:

  • VOUT: Regulated output voltage pin.
  • VIN: Input voltage pin.
  • GND: Ground pin.
  • BYPASS: Bypass pin for noise reduction.
  • ADJ: Output voltage adjustment pin.

What are the Pros and Cons of LDL212PUR?

Pros:

  • High Current Capability: Capable of providing high output current for power-hungry applications.
  • Low Dropout Voltage: Efficient regulation even with small input-output voltage differentials.
  • Stability: Provides stable output voltage under varying load conditions.
  • Compact Package: SOT-223 package offers space-efficient solution for compact designs.

Cons:

  • Heat Dissipation: May require heat sinking for high current applications to prevent overheating.
  • External Components: Some applications may need additional external components for stability or noise reduction.

Are There Any Equivalents/Alternatives to LDL212PUR for Recommendation?

  • The LM2940 from Texas Instruments and the L4931 from STMicroelectronics are alternatives to the LDL212PUR.
  • Equivalents to the LDL212PUR include the LP2985 from Texas Instruments and the MCP1825 from Microchip Technology.
