詳細說明

The LP2952 and LP2953 are micropower voltage regulators with very low quiescent current (130 µA typical at 1-mA load) and very low dropout voltage (typically 60 mV at light load and 470 mV at 250-mA load current). They are ideally suited for battery-powered systems. Furthermore, the quiescent current increases only slightly at dropout, which prolongs battery life.

The LP2952 and LP2953 retain all the desirable characteristics of the LP2951, but offer increased output current, additional features, and an improved shutdown function.

The automatic output discharge pulls the output down quickly when the shutdown is activated.

The error flag goes low if the output voltage drops out of regulation.

Reverse battery-input protection is provided.

The internal voltage reference is made available for external use, providing a low temperature coefficient (20 ppm/°C) reference with very good line (0.03%) and load (0.04%) regulation.

主要特徵

常見問題解答

What is LP2952IM?

The LP2952IM is a low-dropout voltage regulator designed by Texas Instruments. It is capable of supplying up to 250mA of output current with a dropout voltage of 340mV at full load, making it suitable for low voltage applications.

How Does LP2952IM Work?

The LP2952IM regulates the output voltage by comparing a fraction of the output voltage to an internal reference voltage. It adjusts the pass element to maintain a constant output voltage, even when the input voltage and load conditions change. The low dropout voltage allows it to work with very low input voltages.

How Many Pins does LP2952IM have and What are the Functions of the Pinout Configuration?

The LP2952IM is housed in an 8-lead SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • VOUT: Output voltage pin.
  • VIN: Input voltage pin.
  • GND: Ground pin.
  • ADJ: Adjust pin for fine-tuning the output voltage.
  • NR: Noise reduction pin for improving the power supply rejection ratio.

What are the Pros and Cons of LP2952IM?

Pros:

  • Low Dropout Voltage: Suitable for applications with low input voltages.
  • Low Quiescent Current: Operates with low power consumption when in standby mode.
  • Thermal Shutdown: Includes thermal shutdown protection to prevent overheating.
  • Short Circuit Protection: Safeguards the regulator and load from excessive current.
  • Small Package: The 8-lead SOIC package is space-efficient for compact designs.

Cons:

  • Output Current Limit: Limited to 250mA output current, which may be insufficient for high-power applications.
  • External Capacitors: Requires external capacitors for stable operation and noise reduction.
  • Accuracy: May require additional external components for improved output voltage accuracy.

Are There Any Equivalents/Alternatives to LP2952IM for Recommendation?

  • The LM2937 from Texas Instruments is a similar low-dropout voltage regulator offering comparable performance.
  • Alternatives to the LP2952IM include the MCP1700 from Microchip Technology and the LT1761 from Analog Devices.
