Single-output High-Temperature Linear Power Supply Module

ZITN LH42094/LH42095 series Single-output High-Temperature Linear Power Supply Module are precision positive voltage regulators specifically designed for high-temperature and wide-temperature applications. They provide an output that remains stable against variations in input voltage, load current, and ambient temperature. Without requiring an external filter capacitor, the output noise is less than 1mV, and the circuits can operate reliably long-term at a case temperature of 200°C to 250°C. Compared to equivalent international models, they offer even smaller line and load regulation.

• Operating temperature range: 200~250°C
• Output noise: ＜ 1mV

Regarding the core manufacturing technology of single-output high-temperature linear power supply modules, the high-temperature multichip module (MCM) thick-film hybrid integrated circuit process demonstrates crucial value. Starting from two core dimensions-implementation principle and physical structure-this process fundamentally addresses the three major quality risks encountered by measurement while drilling (MWD) instruments during operation. These risks are also the technical bottlenecks that single-output high-temperature linear power supply modules need to overcome under extreme operating conditions, specifically including the high-temperature failure of electronic components, the failure of electrical connections, and the insufficient impact resistance of circuits.
