Description

The LP38500TSX-ADJ is a high-current, fast-response low dropout (LDO) regulator from Texas Instruments (formerly National Semiconductor). It's designed to deliver up to 3A of output current with a typical dropout voltage of only 340mV at full load. The adjustable output voltage makes it versatile for a wide range of applications.

Applications

  • Post regulators for switching supplies
  • Servers
  • Networking equipment
  • Base stations
  • High current microprocessors
  • ASIC power supplies

Features

  • Adjustable Output Voltage: Allows customization of the output voltage to meet specific application requirements.
  • Low Dropout Voltage: Ensures efficient regulation even with small input-output voltage differentials.
  • Fast Transient Response: Maintains stable output voltage during rapid load changes.
  • Overcurrent Protection: Protects the regulator and load from excessive current draw.
  • Overtemperature Protection: Prevents thermal damage by shutting down the regulator at high temperatures.
  • Enable/Disable Control: Allows for efficient power management.
  • Stable with Ceramic Output Capacitors: Provides stable operation with low-ESR ceramic capacitors.

Benefits

  • High Efficiency: Low dropout voltage minimizes power dissipation, maximizing efficiency.
  • Stable Output Voltage: Fast transient response ensures stable voltage regulation under varying load conditions.
  • Protection Features: Overcurrent and overtemperature protection enhances system reliability.
  • Flexibility: Adjustable output voltage enables use in various applications.
  • Simple Design: Stable with ceramic output capacitors simplifies the design process.
