LM1085ISX-3.3 is a Positive Voltage Regulator from Linear Technology. It is a low-dropout “LDO” regulator with an adjustable output voltage of 3.3V. It provides a stable output for microcontrollers, ASICs and other digital circuits. The output voltage can be adjusted from 2.6-4.0V to suit different voltage requirements.The LM1085ISX-3.3 is a 3-Terminal adjustable regulator with a maximum output current of 1 A. It features integrated power on reset and ENABLE control. The output voltage can be adjusted using an external resistor divider. The output of the regulator is protected against over current and thermal overload.The LM1085ISX-3.3 is designed to offer low quiescent supply current, low dropout voltage, low noise and excellent line and load regulation. The regulator is suitable for low voltage applications as it can operate down to 2.6V. It has excellent power throughput, enabling it to work with heavy loads.The LM1085ISX-3.3 is used in a wide range of applications such as automotive, communication systems, portable electronics and power supplies. It is well suited for Field Programmable Gate Array (FPGA) applications. It can also be used for power sub-systems that require distributed power, as it offers multiple outputs of regulated voltage.The working principle of the LM1085ISX-3.3 is based on the error amplifier circuit. This circuit stabilizes the output voltage by comparing the output to the reference voltage. When the output voltage rises above or falls below the reference voltage, the error amplifier outputs a signal to control the output. The error amplifier output is compared to the voltage at the feedback pin. The difference between these two signals is amplified by the error amplifier and is used to regulate the output voltage.The regulator is further protected against overload by a current limiter circuit. This circuit monitors the current that is flowing through the output of the regulator and limits the current when it exceeds the current limit. This prevents the regulator from overheating or being damaged.LM1085ISX-3.3 provides high reliability and superior performance. It is backed with a detailed datasheet and a wide selection of accessories and kits to help you get the most out of your regulator. With its impressive features, the LM1085ISX-3.3 is an ideal choice for a wide range of applications.
