BA00AST is a linear voltage regulator by ROHM Semiconductor. It is used mainly for audio-visual equipment, such as television, radio, audio players and so on. On one side, it is designed for low voltage and energy saving, with features such as direct current output, ultra-low dropout voltage, wide input voltage range and low quiescent current. On the other side, it is low noise, high frequency operation, high speed response and improved angular characteristics. With a wide variety of operation capabilities, BA00AST offers the best solution for audio-visual products.

BA00AST will directly regulate the voltage to the designated output voltage. Its input voltage is 0.5V higher than its nominal output voltage, and its maximum input voltage is 0.1V lower than its output voltage. The maximum dropout voltage is 0.25V, which allows the device to deliver fast response times and improved angular characteristics. The wide input voltage range makes it suitable for applications where noise immunity is a major concern, such as industrial and digital circuits, and allows a high degree of control over the output voltage.

The working principle of the BA00AST is simple and straightforward. When the circuit is activated, a voltage signal is provided to the device. This signal is then regulated by a series of current-limiting diodes, which provide a precise and stable output voltage. When the input signal is higher than the desired output voltage, the device will reduce the output voltage until the desired value is reached, and vice versa when the input signal is lower than the desired output voltage. Thus, the output voltage can be precisely maintained at a predetermined level.

Another key feature of the BA00AST is its low quiescent current consumption, allowing for energy savings and longer life for the device. The quiescent current is kept at a low level by using field-effect transistors (FETs) and by providing low on-resistance. Furthermore, the device has a high frequency operation, enabling the device to switch between different operational states quickly when necessary.

The wide variety of operation capabilities and features offered by the BA00AST make it an ideal voltage regulator solution for audio-visual products. Its low noise and high frequency operation, as well as its wide input voltage range and low quiescent current consumption make it ideal for applications where noise immunity, speed, and energy savings are desired. Furthermore, its precise, stable output voltage and improved angular characteristics make it ideal for digital and industrial circuits. Therefore, BA00AST is the perfect choice for any voltage regulation needs in audio-visual equipment.
