Description

LT1963AEQ-3.3 Voltage Regulator by Linear Technology

The LT1963AEQ-3.3 is a robust low dropout linear regulator (LDO) designed for high-performance applications that require a well-regulated power supply. Crafted by Linear Technology, a leader in analog integrated circuits, this device offers an optimal balance between low dropout voltage, low noise, and fast transient response, making it an excellent choice for sensitive electronic equipment.

Key Features:

  • Output Voltage: The LT1963AEQ-3.3 provides a fixed output voltage of 3.3V, which is ideal for logic circuits and standard digital ICs that require a stable 3.3V supply.
  • High Current Capacity: With an ability to deliver up to 1.5A of continuous output current, this regulator can power a wide range of devices, from simple low-power sensors to more demanding digital processors.
  • Low Dropout Voltage: The device features a low dropout voltage of typically 340mV at full load, ensuring efficient operation even when the input voltage is close to the output voltage.
  • Stable with Low ESR Output Capacitors: The LDO remains stable with ceramic, tantalum, or aluminum electrolytic capacitors, giving designers flexibility in choosing output capacitors.
  • Low Noise: With an output noise as low as 40µV RMS over a 10Hz to 100kHz bandwidth, the LT1963AEQ-3.3 is suitable for noise-sensitive applications like RF circuits and precision instrumentation.
  • Fast Transient Response: The regulator quickly responds to changes in load, maintaining a stable output voltage even during rapid load swings.
  • Thermal Protection: It includes internal thermal shutdown protection that safeguards the device and the system from damage due to overheating.
  • Adjustable Output: While the LT1963AEQ-3.3 is pre-set to a 3.3V output, it also offers the flexibility to adjust the voltage from 1.21V to 20V with an external resistive divider, for applications requiring a custom voltage setting.

Applications:

The LT1963AEQ-3.3 is suitable for a wide range of applications, including but not limited to:

  • High-efficiency linear power supplies
  • Post-regulation for switching supplies
  • Battery-powered devices
  • Microprocessor and logic supply
  • Power management for notebooks and PDAs

Overall, the LT1963AEQ-3.3 from Linear Technology is a high-quality, reliable choice for designers seeking a high-performance voltage regulator that can deliver clean, stable power under a variety of conditions.
