HJ42130 is a dual low dropout, low ripple sequential power-up linear regulator specifically designed for SM470RIBIM-HT, featuring a power-on/power-off reset circuit. It has characteristics such as small size, high reliability, and low thermal resistance of the housing. It consists of a high-performance operational amplifier, power adjustment transistor, reference voltage source, precision delay network, and hold network to generate two sequential power supplies (+3.3V and 1.8V) and a reset signal required by SM470 (see timing diagram for details). This circuit is made using an improved thick film integrated circuit process, which avoids the defect of 'purple spots' caused by gold-aluminum bonding at high temperatures, enhancing the reliability of the device for long-term use in high-temperature environments with a maximum operating temperature of up to 200°C.
