LTC1729CMS8-4.1 Voltage Regulator by Linear Technology

The LTC1729CMS8-4.1 is a high-performance, micropower, low dropout voltage regulator (LDO) designed by Linear Technology, a leader in analog integrated circuits. This regulator is specifically engineered to maintain a consistent 4.1V output voltage, making it an ideal choice for precision applications where a stable voltage supply is critical.

Key Features

  • Output Voltage: Fixed at 4.1V, providing a precise voltage source for sensitive electronics.
  • Low Dropout Voltage: The device offers a low dropout performance, which ensures efficient operation even when the input voltage is close to the output voltage.
  • High Output Current: Capable of delivering up to 150mA of continuous output current, suitable for a variety of applications.
  • Low Quiescent Current: The LTC1729CMS8-4.1 has a low quiescent current of 20µA (typical), making it ideal for battery-powered systems where power conservation is paramount.
  • Stable with Low ESR Ceramic Capacitors: The regulator is stable with ceramic output capacitors that have low equivalent series resistance (ESR), providing flexibility in design and reducing noise.
  • Thermal Protection: Integrated thermal shutdown protection safeguards the device from overheating, enhancing its reliability and longevity.
  • Overcurrent Protection: Built-in overcurrent protection prevents damage to the regulator and the load in the event of a fault condition.
