The SPX2954N-5.0 is a low dropout (LDO) voltage regulator manufactured by Sipex Corporation (now part of MaxLinear). It's designed to provide a stable 5.0V output voltage with a low dropout voltage, making it ideal for battery-powered and other low-voltage applications. This regulator features high accuracy, low quiescent current, and built-in protection features.

Applications:

• Battery-powered devices.
• Microprocessor power supplies.
• Post regulators for switching power supplies.
• Portable instrumentation.
• Linear regulators.

Features:

• Low dropout voltage.
• 5.0V fixed output voltage.
• High output accuracy.
• Low quiescent current.
• Short circuit protection.
• Thermal shutdown protection.

Benefits:

• Provides a stable and accurate 5.0V output voltage.
• Extends battery life due to low quiescent current.
• Protects the regulator and load from damage due to short circuits and over-temperature conditions.
• Simplifies power supply design.
• Improves system reliability.

Additional Details:

The SPX2954N-5.0 has a typical dropout voltage of 380mV at a load current of 250mA. The output voltage accuracy is ±1%. The quiescent current is typically 1mA. The regulator is available in a TO-252 package. The operating temperature range is -40°C to +125°C. The device also features a reverse battery protection. The SPX2954N-5.0 is commonly used in applications where a stable and efficient 5V supply is required from a lower voltage source. The input voltage range is up to 16V.
