US-based power systems supplier MicroPower Direct has released three new models in its MSR78xx series of point-of-load (POL) switching regulators.
The regulators are designed for space-constrained, high-reliability applications across industries such as industrial automation, test and measurement, and embedded power systems—including energy, medical and defense-related applications.
Engineers are increasingly shifting away from traditional linear regulators to improve efficiency, reduce heat and minimize board complexity. The MSR78xx series is engineered to provide reliable, high-efficiency regulation without the overhead of heatsinks or bulky packaging, according to the company.
The new models include the MSR7805BW (0.5 A), MSR7810BW (1 A) and MSR7820CW (2 A). Designed as drop-in replacements for LM78xx linear regulators, the compact modules deliver peak efficiency of 97% and a wide 6.5-36 VDC input range, the company said. A space-saving SIP3 package provides integrated short-circuit and thermal protection.
The regulators offer full power operation from –40° C to 85° C in a low-noise switching design.
The MSR78xx series is tested to EN 55032 Class B EMC standards and meets key IEC 61000-4 immunity levels when used with the recommended input filter.
“Engineers are under pressure to shrink designs, cut heat, and keep costs in check,” said Amy Anahory, CEO of MicroPower Direct. “That’s where the MSR78xx series fits—it improves circuit thermal performance without complicating the rest of the design.”
