K7805-1000R3L 5V 1A DC/DC Converter 90 Leads High-Efficiency Regulator

The Mornsun K7805-1000R3L is a high-efficiency DC/DC converter designed as a drop-in replacement for LM78xx series linear regulators, offering superior power conversion performance in a compact package. With right-angle (90 ) leads, this model provides flexible installation options for horizontal PCB mounting and space-constrained designs.

Operating across a wide input voltage range of 8-36VDC (for +5V output) and 8-27VDC (for -5V output), the K7805-1000R3L delivers a stable 5V output at up to 1000mA or a -5V output at 500mA, depending on configuration. The converter achieves efficiency levels up to 96%, significantly reducing power loss and eliminating the need for external heat sinks-ideal for energy-conscious, thermally sensitive systems.

Designed with switching regulation technology, this converter ensures low ripple and noise, short-circuit protection, and high thermal stability. Its pin-compatible design with traditional LM78xx regulators allows for effortless upgrades, making it an ideal solution for modernizing existing power systems without PCB redesign.
