The HJ42117 series negative voltage regulator is a thick film integrated three-terminal voltage regulator designed for high-temperature environments. The circuit consists of a high-voltage dielectric isolated operational amplifier, power adjustment transistor, constant current source, temperature compensation reference source, anti-reverse diode, and current limiting protection network. It overcomes the disadvantages of large parasitic capacitance and significant leakage in parasitic diodes found in monolithic integrated voltage regulators. The improved thick film integration process avoids the defect of 'purple spots' that can easily form due to gold-aluminum bonding at high temperatures, enhancing the long-term reliability of the device in high-temperature environments. Compared to foreign devices, it includes an internal anti-reverse diode that improves the device's surge resistance. The output voltage is selectable from -5 to -30V, with an output current up to 1.0A and a maximum operating temperature of 200°C. It uses a TO-258 package that effectively reduces the thermal resistance of the device and can be directly replaced with the 42117 series circuits produced by Micropac Industries, Inc. This series of devices can be widely used in harsh environments such as oil logging and programmable power supplies.
