The LT3082IST#TRPBF is a versatile and robust low dropout linear regulator (LDO) capable of delivering up to 200mA of continuous output current. Designed by Analog Devices Inc., this adjustable voltage regulator is a significant component for applications requiring a stable and reliable power supply. Its unique feature lies in its capability to set the output voltage with a single external resistor, providing flexibility across various design requirements.

Key Features

• Wide Input Voltage Range: The device can handle an input voltage range from 1.2V to 40V, making it suitable for a broad array of power sources.
• Adjustable Output: The output voltage can be adjusted from 0V to 40V, providing a high level of customization for specific circuit needs.
• Single Resistor Voltage Setting: The output voltage is set simply by connecting a single resistor, streamlining the design process and reducing component count.
• Low Dropout Voltage: The LT3082IST#TRPBF maintains a low dropout voltage, ensuring efficient operation even when the input voltage is close to the output voltage.
• Stable with Low ESR Ceramic Capacitors: The regulator is stable with ceramic output capacitors, which have lower equivalent series resistance (ESR) than other types, allowing for a more compact and reliable design.
• Thermal Protection: Built-in thermal shutdown and current limit protection safeguard the device and the application from excessive heat and overcurrent conditions.
• Surface-Mount Package: The device is available in a surface-mount package, which is ideal for space-constrained applications.
