The UC285T-2 is a voltage regulator specifically designed for industrial applications, supporting a wide range of output voltages and power levels. This regulator is part of Texas Instruments’ Large Signal Regulators family and can be used in a number of applications, including lighting, instrumentation, power management and automotive. The UC285T-2 is a linear regulator, which means it is able to regulate the output voltage more precisely than its switching counterparts. It also offers high power density, low noise and fast transient response. As with all linear regulators, the performance of the UC285T-2 is dependent on the power supply design.

At the heart of the UC285T-2 is a reference voltage amplifier that compares the input voltage to a reference voltage. If the input voltage is reduced then the amplifier output voltage will decrease and the output voltage will also drop. Conversely, if the input voltage increases then the amplifier output voltage increases and the output voltage will also increase. This type of control allows the UC285T-2 to remain extremely stable, even when the input power is fluctuating or over-loaded. The UC285T-2 has a wide range of features including; adjustable output voltage, current limiting, short-circuit protection and thermal shutdown protection.

The UC285T-2 takes a wide input voltage range of 6-32V and produces an accurate and stable output voltage of up to 1.25V. This makes it suitable for a variety of industrial and automation applications. The device also features a 1MHz bandwidth, allowing it to be used in applications which require high switching frequencies. The regulator is capable of sourcing up to 1.2A and is temperature compensated, allowing it to offer excellent thermal performance and reliability over a wide range of operating temperatures.

The UC285T-2 has a low quiescent current of 7mA and can operate up to −40 ° to 125 °C. This makes it suitable for use in a wide range of applications including industrial, automotive and medical. One interesting feature of the UC285T-2 is its low power consumption. It is rated to draw as little as 120uA when the output is disabled, making it an ideal choice for applications where power consumption is a concern.

The UC285T-2 also provides excellent transient response times and can switch between different output voltages in as little as 2 μs. This makes it suitable for applications which require fast response times, such as switching power supplies or PWM controllers. The UC285T-2 also features a built-in soft-start and current limiting circuit, allowing it to start up at a limited rate. This feature helps protect the regulator from over-stressing and helps to extend its life in harsh environments.

Overall, the UC285T-2 is a high-performance linear regulator that is suitable for a wide range of applications. It offers excellent performance, stability and can operate over a wide range of input and output voltages. The device is also extremely low power, making it suitable for battery-powered applications. With its wide input voltage range and fast switching capabilities, the UC285T-2 is an ideal choice for a variety of industrial, automotive and medical applications.
