The HJ094DY series 1.8V/1.9V/2.5V/3.3V positive voltage regulator is a thick film integrated three-terminal 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 defects of large parasitic capacitance and significant parasitic diode leakage in monolithic integrated regulators. The housing uses an F2-D copper shell, effectively reducing the thermal resistance of the device. The improved thick film integration process avoids the defect of 'purple spots' that easily form during gold-aluminum bonding at high temperatures, enhancing the long-term reliability of the device in high-temperature environments. It features an internal anti-reverse diode that improves the device's surge protection performance. The output current can reach 1.5A, with a maximum operating temperature of up to 200℃, and it can be directly replaced by the 42148 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.
Main features include:
Maximum input voltage +38V Output current 1.5A
Minimum input voltage +7V Internal short circuit protection, soft start, surge protection circuit
