The LT3085MPMS8E#PBF is a versatile and robust adjustable 500mA single resistor low dropout linear regulator (LDO) from Linear Technology, an Analog Devices company. This high-performance regulator is designed for a wide range of applications, from automotive to industrial control systems, and is particularly well-suited for harsh environments due to its extended temperature range.

Key Features

• Adjustable Output: The LT3085's output voltage can be set anywhere from 0V to 80V with a single external resistor, providing flexibility for various design requirements.
• Wide Input Voltage Range: This LDO supports an input voltage range of 1.2V to 80V, which allows it to cater to a broad spectrum of power sources and applications.
• Extended Temperature Range: The device is designed to operate reliably within a junction temperature range of -55°C to 150°C, making it suitable for extreme conditions.
• Low Dropout Voltage: The LT3085 offers a low dropout voltage, which enhances efficiency and allows operation close to the input supply voltage.
• Stable with Low ESR Capacitors: The regulator is stable with ceramic capacitors, which are smaller, more reliable, and have lower equivalent series resistance (ESR) compared to other types of capacitors.
• Thermal Protection: It includes internal thermal limit circuitry that protects the device under over-temperature conditions.
• Current Monitoring: An additional feature of the LT3085 is its current monitor output, which provides an analog representation of the output current for system monitoring purposes.
