RECOM Switching Regulator, 1.5A Maximum Input Current, 1 Output - R-78B-1.5 Series - R-78B3.3-1.5
Choose this RECOM switching regulator to ensure your electrical supply is compatible with your appliances. As it keeps its output voltage to ±0.5% of its rated 3.3V DC value, it gives you a reliable power supply to keep your devices working effectively. By converting up to 91% of its input energy, the unit minimises the energy lost as heat, so there's no need for a heatsink. It produces just 30mV of ripple voltage to eliminate the risk of disruption from electrical noise.
Features & Benefits
• Compact dimensions of 11.5 (W) x 17.5 (H) x 8.5mm (D) to fit easily onto busy circuit boards
• Built-in short-circuit protection automatically resets the power supply after a fault for fast system restarts
• 9mA quiescent current for low energy consumption when not in use
• Works with input voltages between 4.75 and 18V DC for wide compatibility with common power supplies
• Built-in short-circuit protection automatically resets the power supply after a fault for fast system restarts
• 9mA quiescent current for low energy consumption when not in use
