Working Principle

The ZSR285GTA is a precision voltage regulator which uses a resistive divider circuit to adjust the input voltage to a regulated voltage level. The regulator is connected to the power supply circuitry through a resistive divider. The resistance of the resistive divider determines the input voltage of the regulator. The voltage regulator then compares the input voltage with the preset output voltage, and the control circuit adjusts the output voltage to the desired level. This process is called Voltage regulation.The ZSR285GTA is capable of providing voltage regulation from 0V-30V. The ZSR285GTA is also capable of providing superior accuracy in current regulation of up to ±0.15%.The device is designed with an over-voltage protection feature that prevents the output from being higher than the desired level.The ZSR285GTA voltage regulator also includes a temperature-stabilizing control system. This temperature-stabilizing control system is designed to assure temperature stability while maintaining the voltage levels. The temperature-stabilizing control system is designed with proportional connection with the temperature coefficient. This helps to ensure that the ZSR285GTA is able to maintain the same high quality of voltage stabilizing solutions at different temperatures. Finally, the ZSR285GTA also has a temperature trim adjustment feature. This feature allows users to adjust the output voltage as needed. This is an important feature that is designed to ensure that the ZSR285GTA keeps its superior voltage regulation accuracy over the entire operating temperature range.
