SPX2954M3-L-5.

The SPX2954M3-L-5.0/TR is a low-dropout (LDO) voltage regulator manufactured by EXAR Corporation (now part of MaxLinear). Below are its key specifications, descriptions, and features:

Specifications:

  • Output Voltage: 5.0V (fixed)
  • Output Current: Up to 150mA
  • Dropout Voltage: Typically 300mV at full load
  • Input Voltage Range: 2.5V to 12V
  • Line Regulation: ±0.05% typical
  • Load Regulation: ±0.1% typical
  • Quiescent Current: 75µA typical
  • Operating Temperature Range: -40°C to +85°C
  • Package: SOT-23-3

Descriptions:

  • The SPX2954M3-L-5.0/TR is a low-power LDO regulator designed for battery-powered and portable applications.
  • It provides a stable 5.0V output with low dropout voltage, making it suitable for systems with tight voltage margins.
  • The device includes built-in protection features such as current limiting and thermal shutdown.

Features:

  • Low Dropout Voltage: Ensures efficient operation even with small input-output differentials.
  • Low Quiescent Current: Ideal for battery-operated devices to extend runtime.
  • High Accuracy: Tight output voltage tolerance (±2%).
  • Thermal & Current Protection: Safeguards against overheating and short circuits.
  • Small Form Factor: SOT-23-3 package for space-constrained designs.

This regulator is commonly used in consumer electronics, IoT devices, and embedded systems where stable, low-noise power is required.

*(Note: EXAR was acquired by MaxLinear in 2017, but the part retains its original EXAR branding.)*
