Introduction of BA09ST

The BA09ST is an integrated linear voltage regulator designed for applications requiring a single output power supply. It is precision voltage regulator designed to provide a regulated voltage of 9.1V. The BA09ST can be used to obtain an output voltage range of 5V to 28V. The output voltage is set by the external resistive voltage divider and is held at a fixed value regardless of input line conditions. The output current is adjustable from 0.5A to 1.5A, providing a load current of up to 12A, depending on the power dissipation.

Application Field of BA09ST

The BA09ST can be used in a variety of power supply applications such as surge and overvoltage protection, voltage regulation, precision voltage stabilization, and automatic resetting. It is also suitable for applications such as mobile phones, computers, electronic components and lighting.

Features of BA09ST

The BA09ST provides several advantages over conventional linear regulators. It has a wide operating voltage range of 5V to 28V, which can meet a variety of voltage requirements. It also has a high power output capacity of 12A, allowing it to provide enough power for numerous devices. It is also very reliable with a maximum temperature rise of 70°C and low power dissipation.

Working Principle of BA09ST

The BA09ST is a precision voltage regulator designed to provide a regulated voltage of 9.1V. It works by monitoring the output voltage of the device and adjusting the input voltage accordingly. A control circuit using an on-chip control circuit and PWM comparator monitors the output voltage, and then it adjusts the input voltage according to the given voltage level. The device is able to maintain the output voltage constant, even when input conditions change. The device also features a low-power and low-noise design. The low-power features reduce the power consumption of the device, while the low-noise features ensure that the device produces minimal noise.
