R-78Sxx-0.1 Datasheet

COO (Country of Origin):: TW

RECOM Switching Regulator, 11.6mm Length, 8.5mm Width - R-78S Series - R-78S3.3-0.1

To keep DC-powered equipment happy, add this switching regulator from RECOM to your setup. By adjusting an input voltage supply between 0.65 and 3.15V DC to a safe output voltage of 3.3V DC, it helps to protect circuits from damaging undervoltage or overvoltage conditions. Integrated short-circuit protection means this unit shrugs off current faults. As it also comes with over-temperature protection, it reliably handles demanding operations, even when the heat is on.

Features & Benefits

• Compact external dimensions of 11.6 (L) x 8.5 (W) x 10.4mm (D) to fit in limited spaces

• Typical output ripple and noise of 100mV p-p for reduced electrical disturbance

• Vibration resistance for stability in harsh conditions

• Mean time between failures of 78,172,000 hours for lasting use

Applications

• Communication equipment

• Medical technology

• Household appliances

• IoT systems

How efficient is this regulator?

An efficiency rating of 93% means you can Trust that this regulator minimises energy lost as heat during the conversion process.

How do I mount this regulator?

You can mount this regulator by soldering its built-in pins to the through-holes on your board.
