Description

LT1129CQ-3.3#TRPBF Product Overview

The LT1129CQ-3.3#TRPBF is a high-performance low dropout (LDO) voltage regulator from Linear Technology, designed to deliver a fixed output of 3.3 volts. This regulator is capable of supplying up to 700mA of output current with a typical dropout voltage of just 400mV, making it an ideal solution for battery-powered devices and applications requiring efficient power management.

Key Features

  • Output Voltage: Fixed 3.3V output capable of driving up to 700mA of current.
  • Low Dropout Voltage: Typical dropout of only 400mV at full load, optimizing efficiency and battery life.
  • High Efficiency: Designed to maintain high efficiency even at low input voltages, suitable for portable applications.
  • Thermal Protection: Features internal thermal shutdown to protect the device under over-temperature conditions.
  • Stable with Low ESR Capacitors: Compatible with low equivalent series resistance (ESR) capacitors, which reduces output noise and improves transient response.
  • Low Quiescent Current: The quiescent current is low, making it suitable for battery-powered applications where power conservation is critical.

Applications

The LT1129CQ-3.3#TRPBF is versatile and can be used in a wide range of applications, including but not limited to:

  • Portable Electronics
  • Battery-Powered Equipment
  • Microprocessor Supply
  • Power Management for PDAs and Mobile Phones
  • Linear Power Supplies

Quality and Reliability

Linear Technology ensures that the LT1129CQ-3.3#TRPBF meets the highest quality and reliability standards. The device is available in a thermally enhanced 5-lead TO-220 package, which provides excellent power dissipation characteristics. Additionally, it is RoHS compliant and has a lead-free finish, reflecting the company's commitment to environmental sustainability.

Ordering Information

The product is offered in tape and reel packaging, designated by the TRPBF suffix, which facilitates automated assembly processes for high-volume production requirements.
