Application field and Working Principle

The S-1142B30H-E6T2U voltage regulator is mainly used in industrial, automotive and other applications where a regulated output voltage up to 24V is required. It has a wide input voltage range and adjustable output voltage range for quick and easy adjustment. The linear voltage regulator operates on the principle of linear regulation – it controls output voltage by regulating the input to output voltage difference. This is accomplished using an internal error amplifier, which in turn operates an internal series pass transistor.

The error amplifier monitors the output voltage and compares it with the reference voltage. If the output voltage is higher than the reference voltage, the pass transistor is turned off, reducing the output voltage; if the output voltage is lower than the reference voltage, the pass transistor is turned on, increasing the output voltage. The pass transistor follows the instruction given by the error amplifier, responding to output voltage fluctuations and keeping it within the specified range. Thus the output voltage is regulated according to the reference voltage.

The S-1142B30H-E6T2U voltage regulator also offers adjustable output voltage range and fast transient response time, enabling it to provide reliable and stable regulated output voltage. The adjustable output voltage range makes it easy to adjust and customize the output voltage to suit specific application needs. Its ability to respond quickly to output voltage fluctuations reduces the risk of system instability or unexpected shutdowns.
