MicroPower Direct Broadens Point-of-Load Product Line with High-Efficiency Switching Regulators

New MSR78xx Series delivers up to 97% efficiency in SIP3 packages, offering a compact, reliable alternative to LM78xx-style linear regulators.

SOUTH EASTON, Mass., June 17, 2025 /PRNewswire/ -- MicroPower Direct today announced the release of three new models in its MSR78xx series of point-of-load (POL) switching regulators. Designed as drop-in replacements for LM78xx linear regulators, these compact modules deliver up to 2A output current, peak efficiency of 97%, and a wide 6.5–36 VDC input range — all in a space-saving SIP3 package with integrated short-circuit and thermal protection.

"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."

To meet the demands of today's industrial and embedded systems, engineers are increasingly shifting away from traditional linear regulators — not just to improve efficiency, but to reduce heat and minimize board complexity. The MSR78xx series is engineered for exactly that need: reliable, high-efficiency regulation without the overhead of heatsinks or bulky packaging.

The new models include:

• MSR7805BW (0.5A), MSR7810BW (1A), and MSR7820CW (2A)

Key features:

• Up to 97% efficiency (no heatsink required)
  
  
• Short-circuit and over-temperature protection
  
  
• Full power operation from –40°C to +85°C
  
  
• Low-noise switching design
  
  
• Compact SIP3 footprint for streamlined integration

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. These regulators are ideally suited for space-constrained, high-reliability designs across industries like industrial automation, test and measurement, and embedded power systems — including energy, medical, and defense-related applications.
