Introduction

The UC385TDTR-3G3 is an integrated circuit (IC) designed for voltage regulation and protection in linear power systems. It is a three-terminal voltage regulator with an integrated error amplifier for fast transient response and low output impedance. The UC385TDTR-3G3 is a low-dropout (LDO) linear regulator, which combines a precision voltage reference, an adjustable voltage regulator, error amplifiers, current limiting and thermal overload protection circuits into a single 8-pin package.

Application Field

The UC385TDTR-3G3 is ideal for use in a wide range of applications, including automotive, motor control, instrumentation, audio, battery-powered portable device and telecom systems. In automotive applications, it can be used to power electro-mechanical components such as window switches, pedal settings, seatbelts and airbag systems. It is also an excellent solution for powering telecommunication equipment, such as transponders, wireless base stations and cellular phones. In industrial, instrumentation, audio and medical systems, the UC385TDTR-3G3 can be used to provide a constant source of power for sensors, actuators and other critical components.

Working Principle

The UC385TDTR-3G3 operates using a three-terminal linear regulator circuit. It provides a regulated output voltage (Vout) by comparing the regulated voltage across the load to a reference voltage (Vref). The output voltage is set using an external resistor divider network (R1/R2) connected to the Vref terminal. The output voltage is then regulated by driving the control (ERROR) terminal, to compensate for any variations in load and input voltage.The UC385TDTR-3G3 senses the output voltage and compares it to an internal reference voltage. If the output voltage drops, current is driven into the ERROR terminal, increasing the voltage at the output. Conversely, if the output voltage rises, current is driven out of the ERROR terminal, reducing the voltage at the output.The UC385TDTR-3G3 also offers a number of protection features, including current limiting, thermal overload protection, and low dropout voltage. The IC is able to sense the current and shut down if it exceeds the set limit, providing increased safety and reliability. In addition, the device includes a thermal protection circuit which. shuts down the device if it exceeds the safe operating temperature. This helps to prevent against over-heating caused by prolonged use, offering increased reliability and longer device life.
