HJ42129A/B is a low differential pressure, low ripple dual output positive voltage precision regulator designed for high temperature environments. It can provide the internal/external power supply required by DSP/FPGA/μP and meet the power-up sequence requirements. The minimum input voltage difference is 1.0V. It features a small size, high reliability, and flexible usage. It can operate reliably in an environment of 200℃ for a long time. HJ42129A is specifically designed for TMS320F2812-HT and can meet the power-up requirements of TMS320F2812-HT without external capacitor delay. HJ42129B has two enable terminals for 3.3V and 1.9V, allowing customers to select the power-up sequence according to the requirements of the chosen DSP/FPGA/μP. When in use, it only requires adding a capacitor to ground on the enable terminal of the delayed power supply.
Absolute maximum rating:
Input voltage(VCC) +4.5V~+7V Output current (per channelIO)240mA
Operating temperature range(TC) -55~+200(℃) Storage temperature -65~+200(℃)
Maximum power dissipation(TA=25(℃ without heat sink)) 700mW
