Need a stable 12V DC supply for your equipment? This switching regulator from RECOM takes an input voltage anywhere between 15V and 28V DC and outputs a steady 12V DC. Line regulation of ±0.5% and load regulation of ±1% ensure a consistent supply, even if there are fluctuations in supply and demand. High efficiency of 95% reduces heat dissipation, meaning you won't need a separate heatsink. The compact SIP3 package saves space on your board.

• Operating temperature range of -40°C to +85°C makes it suitable for harsh environments
• Ripple and noise of 70 mV Pk-Pk reduce risk of damage due to overheating
• MTBF of 2,182,000h at +85°C for a long service life
• Through-hole mounting creates a strong connection with your PCB

• Military hardware
• Steel mills
• Lifts

Load regulation is the measure of a power supply's ability to output a constant voltage when the output current fluctuates. The smaller the percentage, the more stable the supply.

Line regulation is similar to load regulation in that it's a measure of a power supply's ability to maintain a constant voltage despite fluctuations in current. Load regulation refers to the output, whereas line regulation refers to the input.
