HJ42123 is a low differential pressure dual output precision voltage regulator designed for high temperature environments, with dual output voltages of 2.5V and 3.3V respectively. It consists of a high-performance operational amplifier, power adjustment transistor, reference voltage source, protection network, and more. This circuit is made using an improved thick film integrated circuit process, which avoids the defect of 'purple spots' that can occur with gold-aluminum bonding at high temperatures, enhancing the long-term reliability of the device in high temperature environments, with a maximum operating ambient temperature of up to 200℃. Each output has an independent enable pin that can be used to control the operating state and power-up sequence of each voltage regulator. The minimum input-output voltage difference is 1.5V. It is particularly suitable for powering TMS320F2812 and SM470.
Absolute maximum rating:
Input voltage(VIN1,VIN2) 5~12V Output current (per channelIO) 700mA
