Key Features
- Regulated 5 V output at up to 1.0 A continuous load current with an input voltage range of 6.5 V to 18 V, replacing inefficient linear regulators
- Load regulation of up to 1% ensures stable 5 V output across varying load conditions without external compensation components
- Surface mount SOP package (R-PDMA-G10, 10-pin) enables compact PCB integration with standard SMT reflow assembly
Applications
The R-78AA5.0-1.0SMD is used as a drop-in high-efficiency switching replacement for 78xx linear regulators in designs powered from 6.5 V to 18 V sources such as 12 V industrial rails, where reducing heat dissipation and improving power efficiency are priorities. It is well suited for sensor nodes, industrial I/O modules, and embedded control boards that need a stable regulated 5 V rail at up to 1.0 A without a large heatsink or thermal management area.

Frequently Asked Questions
What input voltage range does the R-78AA5.0-1.0SMD accept and what output does it regulate to?
The R-78AA5.0-1.0SMD accepts an input voltage from 6.5 V to 18 V with a nominal 12 V design point and provides a regulated 5 V output at up to 1.0 A. This 5 V, 1.0 A output makes it a direct high-efficiency replacement for 7805-series linear regulators in industrial and embedded designs.
How does the efficiency of R-78AA5.0-1.0SMD compare to a linear regulator when powered from a 12 V rail?
A linear 7805 regulator dissipates approximately 7 V drop times the load current as heat, so at 1.0 A from a 12 V rail it generates 7 W of heat. The R-78AA5.0-1.0SMD, as a switching regulator, typically achieves efficiency above 85%, reducing heat dissipation to under 1 W at 1.0 A and eliminating the need for a heatsink on most PCBs.
In which SMT board designs is the R-78AA5.0-1.0SMD an appropriate 5 V power solution?
The R-78AA5.0-1.0SMD suits any SMT PCB design that draws up to 1.0 A at 5 V from an unregulated 6.5 V to 18 V source, such as industrial 12 V DIN rail systems, battery-backed control modules, and sensor gateway boards. Its load regulation of up to 1% ensures that 5 V-sensitive microcontrollers and analog circuits receive a stable supply across the full load range.
